Here, we report the J-aggregate structure of a chloroform solvate of 5-t-butyl-2,3-dicyano-6-[4-(dimethylamino)styryl]-pyrazine with a strong intramolecular charge transfer system. The dye was found to form a two-dimensional brick-wall structure s...
2,3-Diaminomaleonitrile (DAMN) was allowed to react with 2,6-heptanedione to produce (2Z)-2-amino-3-[(1E)-3-methylcyclohex-2-enylideneamino]but-2-enedinitrile and (2Z)-2-amino-3-[(1Z)-3-methylcyclohex-2-enylideneamino]but-2-enedinitrile. The react...

A significant spectral change from solution to vacuum-deposited films was observed in a 2,3-dicyanopyrazine dye, 5-t-butyl-6-[4-(dibutylamino) styryl]-2,3dicyanopyrazine. In absorption spectra, a large hypsochromic shift was recognized. On the oth...

6-Substituted 2,3-dicyano-5-[4-(diethylamino)styryl]-7-methyl-6H-1,4-diazepines were applied as red dopants in single-layer organic electroluminescence (EL) devices. EL maxima were observed at around 610 nm and the EL intensity of the 6-alkyl deri...
