ALKOXYSILYL GROUP-CONTAINING ORGANIC EL DYE AND A METHOD FOR PRODUCING THE SAME

Provided is an alkoxysilyl group-containing organic EL dye that can be used for the production of fluorescent silica particles that do not fade. This alkoxysilyl group-containing organic EL dye is represented by the general formula X—Y-Q-Z—Si(R1/sub

Reduction of 4,7-Diphenyl-1,2,5-thia(oxa)diazolopyridines Affording 2,5-Diphenyl-3,4-diaminopyridines and Ring Closure of the Diamines to Fluorescent Azaheterocycles

Reduction of 4,7-diphenyl-1,2,5-thia- (1a-i) and 1,2,5-oxadiazolopyridines (3a and c-e) gave 3,4-diamino-2,5-diphenylpyridines (2a-g), which were converted into the fluorescent triazolo- (5), 1,2,5-selenadiazolo- (6), imidazolo
