Two new V-shaped A-π-D-π-A type compounds, N-butyl-3,6-bis{(E)-2-[5-(dimesitylboryl)thiophen-2-yl]vinyl}carbazole (BBTC) and N-hexyl-3,6-bis[(E)-4-(dimesitylboryl)styryl]-carbazole (BBSC), with trivalent boron and carbazole as electron acceptor and the core of π-conjugated bridge respectively, were synthesized. All these carbazole derivatives can emit strong blue-green fluorescence either in solution or in solid state. Both the absorption and emission band have been greatly red-shifted when trivalent boron was introduced at the terminal as electron acceptor or the phenyls in π-conjugated bridge were replaced by thienyls.

Key words: carbazole derivative, organoboron compound, V-shaped molecule, fluorescence
