Mixed Methyl Aryloxy Rare-Earth-Metal Complexes Stabilized by a Superbulky Tris(pyrazolyl)borato Ligand

Various mixed methyl aryloxide complexes Tp(tBu)'(Me)LnMe(OAr) (Ln = Y, Lu) were obtained in moderate to high yields according to distinct synthesis protocols dependent on the metal size and sterics of the phenolic proligand. The reaction of Tp(tBu,Me)LuMe(2) and Tp(tBu,Me)YMe(AlMe4) via protonolysis with 1 or 2 equiv HOC(6)H(2)tBu(2)-2,6-Me-4 in n-hexane gave the desired complexes Tp(tBu,Me)LnMe(OAr). Corresponding treatment of Tp(tBu,Me)LuMe(2) with the sterically less demanding HOC6H3Me2-2,6, HOC(6)H(3)iPr(2)-2,6 and HOC6H3(CF3)(2)-3,5 led to .- u the formation of the bis(aryloxy) lutetium complexes Tp(tBu,Me)Lu( OAr)(2). Application of a salt-metathesis protocol employing Tp(tBu)'(Me)LnMe(AlMe4) and the potassium aryloxides KOAr made complexes Tp(tBu)'(Me)LnMe(OAr) accessible for the smaller aryloxy ligands as well. All complexes were analyzed by X-ray crystallography to compare the terminal Ln-Me bond lengths and to evaluate the implication of the methyl/aryloxy coordination for the exact cone angles Theta degrees of the [Tp(tBu,Me)] ancillary ligand. Treatment of Tp(tBu)'(Me)LnMe(AlMe4) (Ln = Lu, Y) with HOC(6)H(2)tBu(2)-2,6-Me-4 in the presence of 4-(dimethylamino)pyridine (dmap) produced ion-separated complexes [Tp(tBu)'(Me)LnMe(dmap)(2)][Me(3)AlOC(6)H(2)tBu(2)-2,6-Me-4)]. The thermal instability of Tp(tBu)'(LuMe)-Lu-Me(OC(6)H(2)tBu(2)-2,6-Me-4) was revealed by the formation of (Tp((t)(Bu)(-H)/(tBu)2,Me))Lu(OC(6)H(2)tBu(2)-2,6-Me-4) via intramolecular C-H-bond activation.

Hydrophobization of cellulose oxalate using oleic acid in a catalyst-free esterification suitable for preparing reinforcement in polymeric composites

It is common practice to use cellulose as reinforcement and fatty acid as compatibilizer in the preparation of polymeric composites. However, the used catalysts (e.g., pyridine) are usually toxic and should be avoided. In this study, a new type of microcellulose – cellulose oxalate (COX) was chosen as reinforcement to be reacted with oleic acid to prepare hydrophobic fillers in a catalyst-free esterification for different times. For comparison, microcrystalline cellulose (MCC) was also selected. The success of esterification of COX and oleic acid was confirmed but little esterification occurred when MCC was used. After reacting COX with oleic acid for 18 and 48 h, the products showed stable water contact angles of about 130 degrees C. Composites of polypropylene with COX or MCC were prepared. Tensile tests showed that for a given reaction time, the COX-based composites exhibited higher values of both Young’s modulus and tensile strength than those of MCC-based composites.

Photo-degradation organic dyes by Sb-based organic-inorganic hybrid ferroelectrics

The organic-inorganic hybrid halide compounds have emerged as one of the most promising photoelectric material for their superior optoelectronic properties and hold great prospects for renewable energy substitutes and environmental protection as photocatalysis. Here, we report the optical properties of the Sb-based organic-inorganic hybrid ferroelectric materials: pyridine-4-aminium tetrachloroantimonate ((C5H2N2)SbCl4, sample 1), piperidin-1aminium tetrachloroantimonate ((C5H13N2)SbCl4, sample 2) and tris(trimethylammonium) nonachlorodiantimonate (((CH3)(3)NH)(3)Sb2Cl9, sample 3), which are a kind of exploited efficient photocatalysts. Samples 2 and 3 exhibit distinct photoelectric respond, which are mainly ascribed to their minor narrow band-gap compared with sample 1. For the ferroelectrics, the intrinsic of spontaneous polarization of sample 3 at room temperature is favourable for the separation of photogenerated electrons and holes within the photorespond process. Moreover, sample 3 shows the highest efficiency of photo-decomposed Rhodamine B (90.2% within 80 min) and Methyl Orange (MO) (97.4% within 50 min), thanks to the photo-excited electrons and holes promoting the formation of oxidative radical species during the photo-redox progress. These findings prove that the development of a novel Sbbased organic-inorganic hybrid halide compounds with good stability in the degradation of organic dyes paves a way to designing new photocatalyst.

Accelerating Effect of DMAP on CuI Catalyzed Buchwald-Hartwig C-N Coupling: Mechanistic Insight to the Reaction Pathway

An efficient methodology has been developed for C-N cross-coupling reaction between aryl halide and amine using a catalytic system comprised of CuI and N,N-dimethyl amino pyridine (DMAP). Coupling reactions were carried out in DMSO at 120 degrees C in presence of 5 mol% CuI, 20 mol% DMAP and 2.5 equivalent of KOH. Addition of DMAP was found to be beneficial in accelerating the rate of reaction significantly. Both aryl iodides and aryl bromides could be successfully coupled with different primary and secondary amines to furnish the desired cross-coupling product in high yield. A copper complex [Cu(DMAP)(4)I]I made by combining CuI and DMAP was found to produce superior result for the Buchwlad-Hartwig cross coupling reaction. The use of 2 mol% of the copper complex is sufficient to produce high yield of the product.

Novel low-dielectric constant and soluble polyimides from diamines containing fluorene and pyridine unit

Polyimides (PI’s) with low-dielectric constant and excellent organic solubility have broad application prospects in the electronic field. Herein, this study designed a series of novel, low dielectric, organic soluble PI films by creatively introducing fluorene and pyridine ring into diamine monomers. Because of the noncoplanar structure of fluorenyl and the polarization of pyridine ring, PI films achieved a low-dielectric constant (2.22-3.09 at 10 MHz) and excellent organic solubility. Even in some organic solvents with low-boiling points, these PI films still exhibited outstanding solubility. In addition, all the films possessed high-tensile strength (approximate to 120 MPa) and excellent optical transparency (>70%, 450 nm). It was worth noting that the glass transition temperature of films was all above 280 degrees C and 5% weight loss temperature (T-5%) was at 486-553 degrees C. In general, the novel high-performance low-dielectric PI films are expected to be used in the field of microelectronics.

Structure-Activity Relationship Studies of Pyridine-Based Ligands and Identification of a Fluorinated Derivative for Positron Emission Tomography Imaging of Cannabinoid Type 2 Receptors

The cannabinoid type 2 (CB2) receptor has emerged as a valuable target for therapy and imaging of immune mediated pathologies. With the aim to find a suitable radiofluorinated analogue of the previously reported CB2 positron emission tomography (PET) radioligand [C-11]RSR-056, 38 fluorinated derivatives were synthesized and tested by in vitro binding assays. With a K-i (hCB2) of 6 nM and a selectivity factor of nearly 700 over cannabinoid type 1 receptors, target compound 3 exhibited optimal in vitro properties and was selected for evaluation as a PET radioligand. [F-18]3 was obtained in an average radiochemical yield of 11 +/- 4% and molar activities between 33 and 114 GBq/mu mol. Specific binding of [F-18]3 to CB2 was demonstrated by in vitro autoradiography and in vivo PET experiments using the CB2 ligand GW-405 833. Metabolite analysis revealed only intact [F-18]3 in the rat brain. [18F]3 detected CB2 upregulation in human amyotrophic lateral sclerosis spinal cord tissue and may thus become a candidate for diagnostic use in humans.

Electronic and geometric structure effects on one-electron oxidation of first-row transition metals in the same ligand framework

Developing new transition metal catalysts requires understanding of how both metal and ligand properties determine reactivity. Since metal complexes bearing ligands of the Py5 family (2,6-bis-[(2-pyridyl)methyl] pyridine) have been employed in many fields in the past 20 years, we set out here to understand their redox properties by studying a series of base metal ions (M = Mn, Fe, Co, and Ni) within the Py5OH (pyridine-2,6-diylbis[di-(pyridin-2-yl)methanol]) variant. Both reduced (M-II) and the one-electron oxidized (M-III) species were carefully characterized using a combination of X-ray crystallography, X-ray absorption spectroscopy, cyclic voltammetry, and density-functional theory calculations. The observed metal-ligand interactions and electrochemical properties do not always follow consistent trends along the periodic table. We demonstrate that this observation cannot be explained by only considering orbital and geometric relaxation, and that spin multiplicity changes needed to be included into the DFT calculations to reproduce and understand these trends. In addition, exchange reactions of the sixth ligand coordinated to the metal, were analysed. Finally, by including published data of the extensively characterised Py5OMe (pyridine-2,6-diylbis[di-(pyridin-2-yl)methoxymethane])complexes, the special characteristics of the less common Py5OH ligand were extracted. This comparison highlights the non-innocent effect of the distal OH functionalization on the geometry, and consequently on the electronic structure of the metal complexes. Together, this gives a complete analysis of metal and ligand degrees of freedom for these base metal complexes, while also providing general insights into how to control electrochemical processes of transition metal complexes.

Inhibitory effect of selected hydrocolloids on 2-amino-1-methyl-6-phenylimidazo [4,5-b]pyridine (PhIP) formation in chemical models and beef patties

2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) is a mutagen and a rodent carcinogen mainly formed in thermally processed muscle foods. Hydrocolloids are widely used as thickeners, gelling agents and stabilizers to improve food quality in the food industry. In this study, the inhibitory effects of eight hydrocolloids on the formation of PhIP were investigated in both chemical models and beef patties. 1% (w/w) of carboxymethylcellulose V, kappa-carrageenan, alginic acid, and pectin significantly reduced PhIP formation by 53 %, 54 %, 48 %, and 47 %, respectively in chemical models. In fried beef patties, kappa-carrageenan appeared to be most capable of inhibiting PhIP formation among the eight tested hydrocolloids. 1% (w/w) of kappa-carrageenan caused a decreased formation of PhIP by 90 %. 1% (w/w) of kappa-carrageenan also significantly reduced the formation of other heterocyclic aromatic amines including MeIQx and 4,8-DiMeIQx by 64 % and 48 %, respectively in fried beef patties. Further mechanism study showed that kappa-carrageenan addition decreased the PhIP precursor creatinine residue and reduced the content of Maillard reaction intermediates including phenylacetaldehyde and aldol condensation product in the chemical model. kappa-Carrageenan may inhibit PhIP formation via trapping both creatinine and phenylacetaldehyde. The structures of adducts formed between kappa-carrageenan and creatinine and kappa-carrageenan and phenylacetaldehyde merits further study.

High sensitive pyridine chemiresistive sensors based on azacyclobutane modified perylene bisimide derivatives

A novel bay brominated perylene bisimide derivative with azacyclobutane modified (PBI-1N) was designed and synthesized. The derivative had good solubility in organic solvents and excellent self-assembly properties. The networked structure of PBI-1N was transferred to the surface of the device to prepare the chemiresistive sensor, and its sensing performance was studied. There is a higher sensitivity for PBI-1N-based sensor with experimental detection limit of pyridine reaching 375 ppb. Moreover, the pyridine and its derivatives can be distinguished by introducing halogen bond interaction. This provides a useful reference for the molecular structure design of high performance organic semiconductors in the future.
