2,3-Dichloroquinoxaline and some of its derivatives have been reacted with malononitrile and ethyl cyanoacetate to yield a variety of 3-chloro-2-(cyanomethylene)-1,2-dihydroquinoxaline derivatives. The reaction of 3-chloro-2-(dicyanomethylene)-1,2-dihydroquinoxaline (2e) with pyridine and its methyl derivatives led to the zwitterionic structures 6a-c. The structures of the newly synthesized compounds were assigned by spectroscopic data and elemental analyses.

Electric Literature of 652-12-0, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 652-12-0, Name is Tetrafluorophthalic anhydride,introducing its new discovery.

A series of unsymmetrical dyes containing a naphthyl unit connected to an electron acceptor moiety was designed and synthesised. By modifying the electron acceptor unit, a shift of the LUMO energy level as well as its distribution through the molecule were achieved. These dyes were fully characterised by optical, computational and electrochemical techniques. In addition, crystal structures reveal different packing depending upon the nature of the acceptor. Their potential use as electron acceptor materials for organic photovoltaics (OPVs) was also investigated by photoluminescence studies of blends with the common OPV polymers P3HT and PCDTBT. A series of unsymmetrical dyes was synthesised and characterised. Their optical and electrochemical properties were tuned by modifying the electron acceptor unit. Copyright
