| 摘 要： | 合成了四个对称及不对称含叔丁基吡喃翁方酸的菁染料，通过光谱和元素分析确定其结构，测定了它们的紫外-可见吸收光谱、熔点和溶解性能。结果表明吡喃翁方酸菁染料比一般菁染料具有更长的吸收波长和更好的溶解性能。用Dye2的单晶分子堆积图解释了染料的熔点反常现象。

| Abstract: | Four symmetrical and asymmetrical pyrylium-squarylium cyanine dyes were synthesized. Their structures were confirmed by spectroscopy and element analysis. Absorption spectra, melting points and solubilities were studied. It was revealed that pyrylium-squarylium cyanine dyes had longer absorption wavelength and better solubilites than other squarylium cyanine dyes. The unusual melting points were explained by Dye 2 single crystal packing structue. |
