Over the past decades, there is increasing information about synthesis, characterization and applications of metal complexes including quinoxaline derivative metal complexes. The focus of the review is emphasized on synthesis, characterization, structural analysis, theoretical calculations and biological studies of quinoxaline derivative metal complexes. These types of review provide unique pla...

A series of N-heterocyclic quinoxaline derivatives was successfully synthesized and applied as hole transport layers in quantum dot light-emitting diodes (QLEDs). By inducing sp(2) N-atoms into the quinoxaline backbone, the electron affinity of the obtained material was enhanced, and its optical properties and bandgap became tunable. Quinoxaline based N-heteroacenes show a narrow bandgap, high ...

The ability for density functional theory with the B3LYP lanl2dz basis set to predict 1st (Wave 1) and 2nd 2) reductions of diazine ring in a series thirty-seven (37) 1,4-di-N-oxide quinoxaline-2-carboxamide derivatives dimethylformamide was examined. B3LYP/lanl2dz method had strong correlation low experimental potentials Wave 1 2, respectively. There are nine identifiable analogs based on simi...

In the title mol-ecule, C(24)H(18)N(2)O(3)S, the 13-atom ring system comprising the quinoxaline and fused five-membered ring exhibits an r.m.s. deviation from coplanarity of 0.039 Å, with a maximum deviation of 0.0710 (10) Å for the PhCO-bearing C atom of the five-membered ring. The 10-membered C(8)N(2) quinoxaline ring system has an r.m.s. deviation from coplanarity of 0.022 Å, with a maximum ...

A new quinoxaline-fused tetrathiafulvalene-based sensitizer has been prepared and characterized. The resulting power conversion efficiency of 6.47% represents the best performance to date for tetrathiafulvalene-sensitized solar cells.

A series of indolo[2,3-b]quinoxaline derivatives were efficiently synthesized from 2,3-dibromoquinoxaline by two pathways. A one-pot approach using Pd-catalyzed two-fold C-N coupling and C-H activation reactions gave indolo[2,3-b]quinoxaline derivatives in good yields, but with limited substrate scope. In addition, a two-step approach to indolo[2,3-b]quinoxalines was developed which is based on...

Quinoxaline-based semiconducting materials are currently of high interest in the field of organic photovoltaics. The number of structural variations employed has been, however, quite limited to date. In this paper we report on the synthesis of a series of quinoxaline monomers and triads with improved optical features. This was achieved by using conjugated linkers, i.e. ethenyl, butadienyl and/o...

We report a suitable quinoxaline synthesis using molybdophosphovanadates supported on commercial alumina cylinders as catalysts. These catalysts were prepared by incipient wetness impregnation. The catalytic test was performed under different reaction conditions in order to know the performance of the synthesized catalysts. The method shows high yields of quinoxaline derivatives under heterogen...

Quinoxaline derivatives exhibit a wide range of biological activities and electron transport properties. The presence of electron withdrawing quinoxaline ring has been used in π-conjugated structures to fabricate the OLED materials. In the present investigation, vinyl benzaldehyde capped quinoxaline derivatives were synthesized using 6-methyl-2,3difurylquinoxaline with terephthaldicarboxaldehyd...

In the title compound, C(23)H(24)N(4)O(3)·H(2)O, the 1,3-oxazoline ring is nearly planar [maximum deviation = 0.059 (2) Å] and its mean plane is twisted by 30.12 (8)° with respect to the quinoxaline fused-ring system; the benzene ring is nearly coplanar with the quinoxaline fused-ring system [dihedral angle = 2.52 (2)°]. The water mol-ecule of crystallization is hydrogen-bond donor to an N atom...
