Electrochemistry and Electrogenerated Chemiluminescence of Quinoxaline Derivatives
We report the electrochemistry, spectroscopy, and electrogenerated chemiluminescence (ECL) of donor-acceptor compounds containing a quinoxaline derivative as the central core coupled with fluorene (CFPQ, CFPP, and MFPQ) and triphenylamine moieties (MAPQ). Cyclic voltammetry of all four derivatives show reversible reduction waves (assigned to the formation of the radical anion) localized in the ...
متن کاملSynthesis of tetrazolo [1,5-a]quinoxaline derivatives
Displacement reaction of 2,3-dichloroquinoxaline with secondary amines in boiling ethanol afforded it`s mono aminoquinoxaline derivatives. Further reaction of the latter compounds with sodium azide in warm dimethylsulfoxide achieved a group of 4-amino tetrazolo[1,5-a]quinoxaline derivatives. 1HNMR spectra of these compounds are discussed.
متن کاملMicrowave Assisted Synthesis of Some Quinoxaline Derivatives
The high commercial demand for quinoxalines needs a rapid, greener and safer synthetic method among the chemists. A series of quinoxaline derivatives has been synthesized by condensation of diamines and dicarboniles in microwave heating conditions and in solvent free media. This environmentally benign synthetic approach gives us excellent yields (80-90%) in shorter reaction time (3.5 minutes.)....
متن کاملQuinoxaline derivatives with broadened absorption patterns.
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...
متن کاملQuinoxaline, its derivatives and applications: A State of the Art review.
Quinoxaline derivatives are an important class of heterocycle compounds, where N replaces some carbon atoms in the ring of naphthalene. Its molecular formula is C8H6N2, formed by the fusion of two aromatic rings, benzene and pyrazine. It is rare in natural state, but their synthesis is easy to perform. In this review the State of the Art will be presented, which includes a summary of the progre...
