  Synthesis and properties of 2,7-phenylethenyl- and benzoxazol-2-ylethenyl N-ethylcarbazole derivatives

  摘要：

  A number of new symmetrically and unsymmetrically substituted 2,7-phenylethenyl and benzoxazol-2-ylethenyl N-ethylcarbazole derivatives were synthesized by successive Wittig and Knoevenagel olefinations of 9-ethylcarbazole-2,7-dicarbaldehyde. The resulting compounds showed strong photoluminescence in the blue region. The spectral parameters of unsymmetrically substituted 9-ethylcarbazoles with a donor-donor-acceptor conjugation type are determined by intramolecular interaction in the donor-acceptor fragment.
