Abstract

A novel donor-π-acceptor( D-π-A) type carbazole derivative( L) was designed and synthesized through alkylation, nitration, iodination, Heck cross-coupling reaction and hydrazine hydrate reduction reaction of carbazole. Compound L was characterized by FT-IR,1H NMR,13 C NMR and MS. The optical,electrochemical properties and electronic cloud distribution of compound L were preliminarily studied by means of UV-Vis absorption spectra,fluorescent emission spectra,cyclic voltammogram and theoretical calculation.The results revealed that UV-Vis absorption and fluorescence spectra of compound L red-shifted with the increasing solvent polarity.
