利用Wittig-Horner方法合成了一系列新的基于联吡啶的π-共轭分子, 并用1H NMR, 13C NMR、红外光谱、元素分析和MS进行了表征. 通过热重分析(TGA)测定结果表明所合成的化合物具有良好的热学稳定性; 化合物的光致发光(PL)最大发射峰在439~441 nm之间, 对应于蓝光区域.

A series of novel π-conjugated molecules based on bipyridyl were synthesized by Wittig-Horner reaction. Their structures were characterized by 1H NMR, 13C NMR, IR, MS spectra and elemental analysis. All the compounds synthesized exhibit remarkable thermal stability as determined by thermal gravimetric analysis (TGA). The photoluminescence (PL) emission maximum peaks of materials prepared are in the range of 439~441 nm corresponding to blue light re-gion.

Key words: bipyridyl, blue light, thermal gravimetric unalysis, thermal stability, Wittig-Horner reaction
