| Abstract: | Two novel long conjugated coumarin derivatives,3-(4′-bromophenyl)-7-(N-octyl-3′-bromocarbazole-6′-vinyl)coumarin(6a) and 3-(4′-bromophenyl)-7-4′-methoxyphenyl-1′-vinyl)coumarin(6b),were synthesized by Perkin reaction between 4-methyl-salicylaldehyde with 4-bromo-phenylacetic acid to form coumarin ring,followed by constructing the long congjugated system using Wittig Reaction between coumarin phosphonium salt and aromatic aldehydes.The structures were characterized by UV,1H NMR,IR,MS and fluorescence spectra.The results showed that 6a and 6b exhibited good optical properties with strong fluorescent intensity and large Stokes shift. |
