Abstract

Nine novel carbazolyl diacylhydrazone Schiff-bases were synthesized by alkylation, F-C acylation
and condensation reactions starting from carbazole and hydrazide. The title Schiff-bases were characterized
by 1H NMR, MS, IR and elemental analysis. The synthetic conditions were optimized, and the best
yield of the title Schiff-bases was up to 92.3 %. The relationships between the luminescence properties
and the structures of the title Schiff-bases were studied. The results showed that the introduction of the
Naphthalene-2-yloxy could form great plane conjugate structure to improve their luminescence properties.

Keywords
