合成了12个含香豆素单元的查尔酮化合物,采用1H NMR、13C NMR、MS和元素分析等手段对它们进行了表征,通过测定最大紫外吸收波长、摩尔吸光度、最大荧光发射波长和Stokes shift值等参数。结果表明这类化合物有较大的摩尔吸光度和较小的Stokes位移值,作为发光材料值得进一步研究。
Twelve chalcone compounds with coumarin units were synthesized and characterized by 1H NMR, 13C NMR, MS and elemental analysis. The maximum ultraviolet absorption wavelength, molar absorptivity, maximum fluorescence emission wavelength and Stokes shift and other parameters. The results show that these compounds have larger molar absorptivity and smaller Stokes shift value, which is worth further study as a luminescent material.
