Porous POM/PLLA membranes decorated with gold nanoparticles as flexible and efficient plasmonic substrates for surface-enhanced Raman scattering

In this work, we have developed a flexible and efficient Surface-enhanced Raman scattering (SERS) substrate by a facile way of fabricating gold nanoparticles (NPs) decorated Poly(oxymethylene)/poly(L-lactic acid) (POM/PLLA) membranes. Firstly, POM/PLLA membranes were aminolyzed by 1,6-hexanediamine to render the membranes with amino groups and porous structure simultaneously. The membranes were then immersed in tetrachloroauric acid (H4AuCl4) solution, where the AuCl4- anions were able to complex with the free amine groups of POM/PLLA, followed by in situ reduction by sodium borohydride to immobilize Au NPs on POM/PLLA membranes. The POM/PLLA/Au membranes exhibited high SERS sensitivity as well as good Raman signal reproductivity for rhodamine 6G (R6G). The minimum detection concentration was 10(-14) M and the enhancement factor was calculated to be 1.54 x 10(9).

Ultrasound assisted one-pot synthesis of 1,2-diaryl azaindoles via Pd/C-Cu catalysis: Identification of potential cytotoxic agents

Ultrasound assisted one-pot and direct access to 1,2-diaryl substituted azaindole derivatives has been achieved via the sequential N-arylation followed by coupling-cyclization under Pd/C-Cu catalysis. The methodology involved initial C-N bond forming reaction (step 1) between an appropriate o-bromo substituted amino pyridine and iodoarene followed by C-C and C-N bond formation (step 2) between the resulting N-aryl substituted intermediate and a terminal alkyne in the same pot. A variety of azaindoles was prepared by using this method. These compounds were assessed for their cytotoxic properties against two different metastatic breast cancer cell lines. Compounds 4i, 4k and 4o showed promising growth inhibition of these cell lines and SIRT1 inhibition in vitro. (C) 2019 Elsevier Ltd. All rights reserved.

An excellent bipolar host material exhibiting EQE of 24.0% with small efficiency roll-off in solution-processable thermally activated delayed fluorescence OLEDs

Highly soluble functional materials acting as hosts for thermally activated delayed-fluorescence (TADF) emitters are urgently needed to stimulate the development of cost-effective, solution-processable, high-performance organic light-emitting diodes (OLEDs). An organic material, 10-(6-(9H-carbazol-9-yl)pyridin-3-yl)-9,9-diphenyl-9,10-dihydroacridine (APC), was designed and facilely synthesized by integrating electron-donating diphenyl acridine and carbazoles at the 2- and 5-positions of electron-accepting pyridine (D-A-D’ type architecture). The high triplet energy (2.82 eV), thermal robustness (thermal decomposition beyond 350 degrees C), appropriate highest occupied molecular orbital and lowest unoccupied molecular orbital energy levels, balanced charge-carrier transport ability, and good solubility of APC supported its designation as a host material for solution-processable TADF-OLEDs. Two different types of TADF OLEDs were fabricated by varying the hole transport material (HTM) while consistently using APC as the host and familiar t4CzIPN as the green TADF emitter, and their device characteristics were compared. At first, the devices fabricated using PVK as HTM (ITO/PEDOT:PSS/PVK/EML/TPBi/LiF/Al) that could use an orthogonal solvent system displayed a state-of-the-art performance with external quantum efficiency (EQE)/current efficiency (CE)/power efficiency (PE) as high as 24.0%/82.2 cd A(-1)/46.9 lm W-1, respectively. In particular, over 90.0% of EQE was retained (EQE of 21.7%) at the practical luminance of 1000 cd m(-2), which is advantageous for display technology. Another class of devices was fabricated by replacing PVK with our recently reported thermally cross-linkable X-TPACz as the HTM, realizing a very low turn-on voltage (2.9 V) and excellent PE of 70.1 lm W-1 (with a similar EQE of 22.8%), which could be very effective for lighting equipment. These excellent outcomes demonstrate the potential of APC as a host material for future solution-processable display and lighting technologies.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 545445-44-1. Computed Properties of C20H25N3O3.

Complex core-shell morphologies of block copolymers revealed beneath the surface

This paper identifies and characterizes complex core-shell morphologies in thin films of a polybutadiene-block-poly( 2-vinyl pyridine)-block-poly(tert-butyl methacrylate) (BVT) triblock terpolymer. The spin-coated BVT film develops into two distinct microphase separated structures with thickness variation during solvent annealing in a well-controlled atmosphere of THF vapor. Cylinders parallel to the film plane are found in thinner terraces and featureless areas that are characteristic of the lying lamella phase, or disordered structures are found in thicker terraces. Underneath the surface, we found that these microphase separated structures exhibit core-shell morphologies, i.e. surface ablation revealed core-shell cylinders and core-shell perforated lamellae under a cover layer in each terrace. Time-resolved study upon solvent annealing shows that the dynamics of microdomain evolution are affected by the extent of annealing time. The structural development in the BVT terpolymer films on corrugated supports demonstrates flow-field-induced sequenced ordering of the microdomains.

Synthetic Route of 545445-44-1, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 545445-44-1 is helpful to your research.

Catalytic hydrogenation, hydrocracking and isomerization reactions of biomass tar model compound mixture over Ni-modified zeolite catalysts in packed bed reactor

Gas-phase conversion of a model mixture of biomass tar (5 wt% naphthalene and 95 wt% of 1-methylnaphthalene) into 2-methylnaphthalene liquid product and ethylene and propane gas mixture was carried out over different zeolites and metal promoted zeolites in a packed-bed reactor for the first time. In the present work, a series of MFI (H-ZSM-5), BEA (H-beta), FAU (H-Y, H-USY), and MOR (H-Mordenite) zeolites were investigated. The effect of Ni metal addition on the promotion of parent zeolite catalysts was studied. The most successful catalysts were characterized by BET, ICP-AES, XRD, HRSEM, STEM-HAADF, and STEM-BF with EDXS, NH3-TPD, H-2-TPR, TGA, and pyridine-DRIFT techniques. The superior performance in comparison to the other studied catalysts was established over the 5 wt%Ni/H-ZSM-5 (SiO2/Al2O3 = 30) with 96.2 mol% of selectivity to 2-methylnaphthalene in the liquid phase, 90 mol% total conversion with the highest part (82.9 wt%) of ethylene and propane in the gas phase after 24 h time-on-stream. This high catalytic performance of the 5 wt%Ni/H-ZSM-5 catalyst can be attributed to the presence of the high mesopore volume, pore diameter, and high mesopore surface area, the existence of the redox active sites, and the presence of strong Lewis acid sites due to synergetic interaction between Ni metal species and zeolite acid support. Based on the product distributions observed, the reaction scheme of the conversion of biomass tar model mixture of naphthalene and 1-methylnaphthalene over studied catalysts was proposed. Our catalytic results obtained over pristine and Ni-modified zeolite catalysts shed light on the potential use of these catalysts in the biomass tar valorization process under atmospheric pressure.

Synthesis and characterization of tridentate phosphine ligands incorporating long methylene chains and ethoxysilane groups for immobilizing molecular rhodium catalysts

The new tridentate phosphine ligands EtOSi((CH2)(n)PPh2)(3) and O[Si((CH2)(n)PPh2)(3)](2) (n = 4, 7, 11), as well as their precursor ethoxysilanes EtOSi((CH2)(m)CH = CH2)(3) and disiloxanes O[Si((CH2)(m)CH = CH2)(3)](2) (m = 2, 5, 9) and EtOSi(CH2)(11)PPh2RhClCOD)(3) (COD = cyclooctadiene) have been synthesized and fully characterized. The ethoxysilane- and disiloxane-containing phosphine ligands have been immobilized on silica via covalent siloxane bonds. The immobilized linkers have been characterized by P-31 and Si-29 CP/MAS and HRMAS NMR spectroscopy. The covalent siloxane bonds between the linkers and the silica surface prevent translational mobility of the phosphines. Immobilized Wilkinson-type Rh hydrogenation catalysts have been obtained by ligand exchange of ClRh(PPh3)(3) and ClRhpyCOD (py = pyridine) with the surface-bound ligands. The single crystal X-ray structure of ClRhpyCOD has been reported. The activities and lifetimes have been studied for the hydrogenation of 1-dodecene. The new catalysts are highly active and they can be recycled up to 15 times without major loss of activity. Within the first hours of the catalytic reaction the initially molecular complexes form Rh nanoparticles with a narrow size ‘distribution on the surface. The nanoparticles do not leach into the supernatant solution and are not air-sensitive.

Amino-3,5-Dicyanopyridines Targeting the Adenosine Receptors. Ranging from Pan Ligands to Combined A1/A2B Partial Agonists

The amino-3,5-dicyanopyridine derivatives belong to an intriguing series of adenosine receptor (AR) ligands that has been developed by both academic researchers and industry. Indeed, the studies carried out to date underline the versatility of the dicyanopyridine scaffold to obtain AR ligands with not only a wide range of affinities but also with diverse degrees of efficacies at the different ARs. These observations prompted us to investigate on the structure-activity relationships (SARs) of this series leading to important previously reported results. The present SAR study has helped to confirm the 1H-imidazol-2-yl group at R-2 position as an important feature for producing potent AR agonists. Moreover, the nature of the R-1 substituent highly affects not only affinity/activity at the hA(1) and hA(2B) ARs but also selectivity versus the other subtypes. Potent hA(1) and hA(2B) AR ligands were developed, and among them, the 2-amino-6-[(1H-imidazol-2-ylmethyl)sulfanyl]-4-[4-(prop-2-en-1-yloxy)phenyl]pyridine-3,5-dicarbonitrile (3) is active in the low nanomolar range at these subtypes and shows a good trend of selectivity versus both the hA(2A) and hA(3) ARs. This combined hA(1/)hA(2B) partial agonist activity leads to a synergistic effect on glucose homeostasis and could potentially be beneficial in treating diabetes and related complications.
