一类蓝色有机发光材料的合成及荧光性能研究

以4,4-(二乙氧基膦酸)联苯苄酯和芳香醛(或肉桂醛)为原料,碱催化下,在DMF溶液中,经过Wittig-Horner反应,合成了7种含苯乙烯基联苯类化合物。利用MS,1H NMR或元素分析表征了化合物的结构,采用紫外光谱和荧光光谱研究了化合物的光谱性能。结果表明,所合成的化合物是一种较为理想的蓝光材料。

Study on the synthesis and photoluminescence property of blue organic emitting materials

A series of π-conjugated compounds with biphenyl chromophore were synthesized from 4,4'-bis(diethoxy phosphonomethyl)-diphenyl and aromatic aldehydes(or cinnamaldehyde) by Wittig-Horner reaction with alkali-assisted catalysis in DMF solution.MS,proton NMR or element analysis experiments were carried out for characterizing the structures of the synthesized products,and the ultraviolet absorption spectrometry,emission spectrometry and fluorescence spectrophotometry techniques were used for checking their spectra properties.As a result,the photoluminescence study displays that the so-prepared compounds have potential application as blue luminescence materials.
