Abstract
Trimethylsilyl trifluoromethanesulfonate mediated dimerization reaction of vinylogous carbamates of carbazoles gave highly fluorescent pyridocarbazoles through a Povarov-type formal [4 + 2] cycloaddition-retro-aza-Michael cascade. The developed strategy was used to access indolo pyridocarbazole and quinolizinocarbazolone in an expeditious manner. Various coupling reactions were successfully performed on synthesized pyridocarbazoles to study the effect of electronics of substitution on photophysical properties. Synthesized carbazoles possess excellent photophysical properties with high quantum yields (ΦF). Fluorescent carbazole dicarboxylic acid showed potential as a pH probe to give a linear response to pH over a very wide range (7.0-3.0) reflecting high efficiency.
