Blue OLEDs are still a challenge of today’s photoelectrochemistry. The third generation of OLEDs is based on thermally activated delayed fluorescence (TADF). A series of heteroleptic iridium(III) imidazo[1,5-a]pyridine and -quinoline complexes with potential TADF behaviour was synthesized and characterized via UV-Vis absorption and fluorescence spectroscopy as well as measurements of the excited state lifetime. The experimental results were confirmed by computational calculations of the relative energy of the first excited singlet and triplet states. In addition, the HOMO and LUMO levels were calculated with DFT and compared to values estimated from redox potentials determined by cyclic voltammetry. For the first time, a TADF mechanism of these compounds has been proven.

We report here the discovery of a novel ketoreductase (KRED), named KmCR2, with a broad substrate spectrum on bioreduction of sterically bulky diaryl- and aryl(heteroaryl)methanones. The position of the substituent on aromatic rings (meta versus para or ortho) was revealed to control the stereospecificity of KmCR2. The stereoselective preparation of both enantiomers of diaryl- or aryl(heteroaryl)methanols using strategically engineered substrates with a traceless directing group (bromo group) showcased the potential application of this substrate-controlled bioreduction reaction. The combined use of substrate engineering and protein engineering, was demonstrated to be a useful strategy in efficiently improving stereoselectivity or switching stereopreference of enzymatic processes.

A new family of eight heterobimetallic Cu(i)-dppf complexes of general formula [Cu(dppf)L][BF4] with dppf = 1,1 ‘-bis(diphenylphosphino)ferrocene and L representing N,N-, N,O- and N,S-heteroaromatic bidentate ligands have been synthesized and fully characterized by classical analytical, spectroscopic and electrochemical methods. The single crystal structures of [Cu(dppf)(pBI)][BF4] (6), [Cu(dppf)(dpytz)][BF4] (7) and [Cu(dppf)(5-Aphen)][BF4] (8) complexes (where pBI = 2-(2-pyridyl)benzimidazole, dpytz = 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine and 5-Aphen = 1,10-phenanthrolin-5-amine) were determined by X-ray diffraction studies. Cytotoxicity of all complexes was evaluated in two human breast adenocarcinoma cell lines (MCF7 and MDAMB231). All the complexes exhibit high cytotoxicity against both human breast cancer cells with IC50 values far lower than those found for the antitumor drug cisplatin in the same cell lines. The IC50 values on primary healthy fibroblasts are of the same order of magnitude as those found for the tumoral cells.

Several palladium(ii) and platinum(ii) complexes (1-20) of general formula [M(L-n)(X)(Y)] [M = Pd, X = Y = Cl (1-Cl-4-Cl), X = Y = OAc (1-OAc-4-OAc); M = Pt: X = Y = Cl (5-8); M = Pd, X = Cl, Y = CH3 (9-12); M = Pt, X = Cl, Y = CH3 (13-16) or X = Y = CH3 (17-20); n = 1-4] have been synthesized by reaction of different Pd(ii) and Pt(ii) derivatives with various 3-substituted 1-(2-pyridyl)-imidazo[1,5-a]pyridines; i.e.L-n = 1-(2-pyridyl)-3-arylimidazo[1,5-a]pyridine (aryl = Phenyl, L-1; 2-o-Tolyl, L-2; Mesityl, L-3) and 1-(2-pyridyl)-3-benzylimidazo[1,5-a]pyridine (L-4). Detailed spectroscopic investigation (including IR, mono- and bi-dimensional H-1 NMR) and elemental analysis has been performed for all these species, allowing their complete characterization. L-n act as N,N-bidentate ligands and coordinate the metal centers in a chelate fashion through the pyridyl (N-py) and the pyridine-like nitrogen atom of the imidazo[1,5-a]pyridine group (N-im). The X-ray structural analysis performed on two of Pd(ii) and three Pt(ii) complexes, namely [Pd(L-2)(CH3)Cl] (10), [Pd(L-3)(CH3)Cl] (11) and [Pt(L-1)Cl-2] (5), [Pt(L-4)Cl-2] (8), [Pt(L-2)(CH3)Cl] (14) confirmed the spectroscopic and analytical data. Finally DFT studies unveiled the structural reasons behind the inertia of the synthesised compounds toward metalation, identified as the higher angle steric strain in comparison with the analogous bipyridine complexes.

Blue emitting phosphorescent materials with high efficiency and high stability are a key requirement for the wider adoption of organic light emitting devices (OLEDs). In order to achieve triplet derived emission at the higher energy region of the electromagnetic spectrum, a series of neutral, monocyclometalated gold(iii) complexes with trifluoromethyl and trifluoromethoxy functionalized 2-phenylpyridine (ppy) derivatives, 2-anilinopyridine (apy), 2-benzoylpyridine (bpy) and 2-benzylpyridine (bepy), as the cyclometalating framework and diaryl or monoaryl alkyne as ancillary ligands have been designed and synthesized. Extensive photophysical and chemical characterization by various nuclear magnetic resonance spectroscopy techniques, elemental analysis and single crystal X-ray diffraction studies of selected compounds was carried out to confirm the structural and the chemical identity of the complexes. The emission wavelength maxima of the complexes appear in the blue/sky blue region of the electromagnetic spectrum. Detailed photophysical investigations revealed that the different emission properties of the complexes are predominantly dictated by the electronic properties of the cyclometalating ligand. The interesting photoluminescence properties along with the facile synthetic access makes this a promising concept to obtain highly suitable blue emitting gold(iii) complexes.

Three asymmetric tridentate acyl hydrazone Schiff base ligands namely L1, L2 and L3 were prepared via condensation of 4-methoxybenzohydrazide with picolinaldehyde, 1-(pyridin-2-yl)ethanone and phenyl(pyridin-2-yl)methanone respectively. Three bio-relevant mononuclear zinc(ii) complexes [Zn(L1)Cl-2]2H(2)O (1), [Zn(L2)Cl-2] (2) and [Zn(L3)Cl-2] (3) were synthesized by treatment of zinc(ii) chloride with the corresponding Schiff base ligands and characterised by the usual physicochemical techniques. The solid state structures of complexes 1 and 3 were evaluated by single crystal X-ray analysis. All complexes were able to hydrolyse the P-O bond of the phosphate monoester in 90% (v/v) DMSO-water medium using 4-nitrophenylphosphate (4-NPP) as the model substrate and the trend in their activity is 1 approximate to 2 > 3. On considering the highly efficient hydrolysis properties, complexes 1-3 were tested as potential therapeutic agents for cancer using HCT116 (human colorectal carcinoma), HepG2 (human hepatocellular carcinoma) and A549 (human non-small lung carcinoma) cells. Complex 2 showed the highest IC50 values for anti-cancer activity towards all three cell lines among the three complexes and complex 3 showed the least activity as observed in the phosphatase activity study. The internucleosomal degradation of DNA during apoptosis can be detected by cell death detection ELISA. DNA fragmentation that leads to cell death was examined and when induced by complex 2 in HepG2 cells a significant level of DNA fragmentation was observed at regular intervals of time.

Pyridotriazoles are utilized as robust building blocks to access alpha-secondary and alpha-tertiary pyridines via the development of a simple yet practically useful metal-free denitrogenative C-C cross-coupling with boronic acids. The reaction shows a high level of functional tolerance, broad substrate scope, and facile scalability. The synthetic potential of the method is demonstrated by the strurctural modification of a bioactive molecule and concise synthesis of pheniramine analogs.

Flavin-dependent ‘ene’-reductases (EREDs) are highly selective catalysts for the asymmetric reduction of activated alkenes. This function is, however, limited to enones, enoates, and nitroalkenes using the native hydride transfer mechanism. Here we demonstrate that EREDs can reduce vinyl pyridines when irradiated with visible light in the presence of a photoredox catalyst. Experimental evidence suggests the reaction proceeds via a radical mechanism where the vinyl pyridine is reduced to the corresponding neutral benzylic radical in solution. DFT calculations reveal this radical to be dynamically stable, suggesting it is sufficiently long-lived to diffuse into the enzyme active site for stereoselective hydrogen atom transfer. This reduction mechanism is distinct from the native one, highlighting the opportunity to expand the synthetic capabilities of existing enzyme platforms by exploiting new mechanistic models.
