A convenient and environment-friendly solvent-free procedure was developed for the one-pot synthesis of imidazoles by multicomponent cyclocondensation of 1,2-phenylenediamine or benzil with aromatic aldehydes and NH₄OAc. On comparing the new method with the classical reaction condition, this new synthetic method shows many advantages, such as high yields, easy set-up, and mild reaction conditions.

Wang, Yue published the artcileNovel phosphorescent triptycene-based Ir(III) complexes for organic light-emitting diodes, Recommanded Product: 1,2-Diphenyl-1H-benzo[d]imidazole, the publication is Dalton Transactions (2019), 48(43), 16289-16297, database is CAplus and MEDLINE.

A series of charge-neutral cyclometalated iridium(III) complexes (1-3 and 5-7) containing triptycene-substituted ligands (tbt and tpbi) and two parent complexes (4 and 8) were synthesized and characterized. The crystal structures indicated that π-π stacking interactions existed in ligand tbtH, but not in complex 6. However, a large intramol. repulsion was found in complex 6. These triptycene-based complexes exhibited good thermal stability, which was higher compared with that of the parent complexes. These complexes showed green to yellow emission with peaks that ranged from 503 to 563 nm. The introduction of the rigid non-conjugate triptycene skeleton caused a slight emission red shift (<25 nm), but a significant increase in the PLQYs (>47%) was observed The electroluminescent devices employing 2 and 6 as phosphors displayed impressive performance improvements and low efficiency roll-off because of the higher PLQYs and HOMO levels of these triptycene-based complexes. The maximum current and external quantum efficiencies of the devices based on complexes 2 and 6 were 41.7 cd A^-1, 11.9% and 41.2 cd A^-1, 12.6%, resp., which were about 31% higher than that of the devices based on the parent complexes 4 and 8. This work provides a novel approach to develop highly efficient phosphors with a triptycene skeleton.

2-(Arylamino)aryliminophosphoranes, easily obtained from 2-nitrosodiarylamines,were found to be convenient starting materials for simple reactions with common acylating reagents such as acid chlorides and the Vilsmeier reagent. The reactions allowed for the synthesis of 1,2-disubstituted benzimidazoles or dibenzo[b,e][1,4]diazepines, depending on the substituents on the 2-arylamine nitrogen atom.

A simple, efficient and clean approach for the synthesis of diverse dihydroisoquinolino[2,1-a]quinazolinones, 2-aryl quinazolinones and analogs through intramol. acceptorless dehydrogenative coupling has been achieved. The combination of bis(2-methoxyethyl)ether and mol. oxygen was identified as a highly efficient system for this oxidative dehydrogenative coupling sequential transformation without an external initiator, catalyst and additive. The applicability and practicability were demonstrated by a scope of twenty-nine examples and a gram-scale reaction. Some control experiments were also conducted to support a possible reaction pathway.

Cui, Yang published the artcileDi-/trinuclear cationic Ir(III) complexes: Design, synthesis and application for highly sensitive and selective detection of TNP in aqueous solution, COA of Formula: C19H14N2, the publication is Sensors and Actuators, B: Chemical (2017), 314-322, database is CAplus.

Novel di- and trinuclear cationic iridium(III) complexes with flexible chain functionalized triazole-pyridine moieties as bridging ligands, namely DC-Ir and TC-Ir, were successfully synthesized and their photophys. and electrochem. properties studied. Despite DC-Ir and TC-Ir have different numbers of iridium(III) cores, the almost identical emissions in both solutions and aggregation states were observed Theor. calculations were performed to investigate their electronic structures and rationalize the photophys. and electrochem. behaviors. Compared with the emission in the solution, they exhibit enhanced photoluminescence in the aggregation states. Benefiting from the high emission in aqueous solution, DC-Ir and TC-Ir were employed as the “turn-off” sensors to detect the explosives. The results reveal that DC-Ir and TC-Ir show fast and highly sensitive and selective detection towards 2,4,6-trinitrophenol (TNP) owing to the efficient photo-induced electron transfer as well as the strong electrostatic interaction.

A transition-metal-free, K₂S₂O₈-mediated intramol. oxidative nitrogenation/oxygenation of C(sp³)-H in N-aryl benzylic amines followed by oxidation at the benzylic center has been developed for the synthesis of benzamidine/benzoxazine heterocycles, providing an expedient access to quinazolin-4(3H)-ones, N-aryl-2-arylbenzimidazoles, and 4H-3,1-benzoxazin-4-ones. A considerable amount of work dealing with the mechanistic study to understand the crucial intramol. cyclization step largely favors an iminium ion as the key intermediate.

The transesterification of 1,1,1,3,3,3-hexafluoroisopropyl acrylate (HFIPA) homopolymers and block copolymers with Me acrylate (MA) or Bu acrylate (n-BuA) were investigated for the efficient synthesis of p-type and n-type organic semiconductor acrylates. HFIPA, MA, and n-BuA are readily prepared in a one-pot synthesis by Cu(0) reversible deactivation radical polymerization in high yield with low dispersity to give poly(HFIPA)₁₀₀, PMA₁₀₀-b-poly(HFIPA)_x, and PnBuA₁₀₀-b-poly(HFIPA)_x (x = 100, 50,25). The transesterification of poly(HFIPA)₁₀₀ was also studied using ¹⁹F NMR spectroscopy. Based on this method, a series of eight homopolymers and three copolymers based on semiconductor motifs commonly found in organic light-emitting diodes, organic thin-film transistors, and organic photovoltaics were synthesized with narrow dispersity and conversions up to 99%. These experiments demonstrate that poly(HFIPA) can provide a useful building block in the synthesis of organic electronic materials, providing a simpler route to complex materials which may be challenging to access directly via controlled radical polymerization © 2018 Wiley Periodicals, Inc.

Jayabharathi, J. published the artcileSynthesis of some fluorescent benzimidazole derivatives using cobalt(II) hydroxide as highly efficient catalyst – spectral and physico-chemical studies and ESIPT process, Application of 1,2-Diphenyl-1H-benzo[d]imidazole, the publication is Photochemical & Photobiological Sciences (2013), 12(10), 1761-1773, database is CAplus and MEDLINE.

Some fluorescent benzimidazole derivatives have been designed and synthesized using cobalt(II) hydroxide as highly efficient catalyst. Synthesized compounds have been characterized by ¹H and ¹³C-NMR and mass spectral anal. The solvent effect on the absorption and fluorescence bands has been analyzed and supplemented by computational studies. Solvatochromic effects on the spectral position and profile of the stationary fluorescence spectra clearly indicate the charge transfer (CT) character of the emitting singlet states of all of the compounds studied in both polar and non-polar environments. The fluorescence decays for the benzimidazoles fit satisfactorily to a single exponential kinetics. HOMO and LUMO orbital pictures [DFT/B3LYP/6-31G(d,p)] evidence the existence of excited state intramol. proton transfer (ESIPT) in benzimidazole derivatives containing a hydroxy group.
