以N-烷基咔唑作为电子给体和共轭桥中心, 二米基硼作为端基电子受体, 合成了两个V形A-π-D-π-A型新化合物: 3,6-二{[(E)-2-(5-二米基硼)噻吩]乙烯基}-N-丁基-咔唑 {N-butyl-3,6-bis{(E)-2-[5-(dimesitylboryl)thiophen-2-yl]-vinyl}-carbazole, BBTC}和3,6-二[(E)-(4-二米基硼)苯乙烯基]-N-己基-咔唑, {N-hexyl-3,6-bis[(E)-4-(dimesitylboryl)-styryl]-carbazole, BBSC}. 这两个化合物在蓝绿光波段都有较强的荧光发射. 光谱数据表明, 扩大共轭体系并在端基引入含硼基团导致吸收谱和发射谱显著红移, 并增大分子内电荷转移.

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
