Latest Patents
Among his latest patents, Fox has developed substituted cyclopentadiene electron transport compounds. These novel tetrasubstituted dicyanomethylene cyclopentadienes serve as effective electron-transport agents in positively-charged electrophotographic elements. The compounds are characterized by a specific formula, where R1 and R4 can be independently selected from lower alkyl, halogen, and cyano groups. Additionally, he has created benzofuran dyes containing a coumarin nucleus. This dye features a 6-tertiary amino-2-(Z.dbd.CH--)benzofuran structure, where Z represents atoms that provide an electron-withdrawing group and a conjugated methine linkage. These dyes are formed by condensing a 6-tertiary amino-2-formylbenzofuran with an electron-withdrawing dye nucleus precursor, resulting in bathochromically shifted absorption peaks.
