摘要
利用Perkin反应和Wittig反应设计并合成了两个新型的香豆素衍生物——3-(4'-溴苯基)-7-(N-辛基-3'-溴咔唑-6'-乙烯基)香豆素(6a)和3-(4'-溴苯基)-7-(4'-甲氧基苯基-1'-乙烯基)香豆素(6b),其结构经UV,1H NMR,IR,MS和荧光光谱表征。研究结果表明,6a和6b具有荧光强度大和Stokes位移(分别为115 nm和122 nm)大的特点。
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 ) eoumafin(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.
