摘要：本文合成了七个Ｎ－烷基取代吲哚环的方酸菁染料，通过红外光谱、核磁共振氢谱、质谱与元素分析确认其结构．测定它们的电子吸收光谱、熔点、溶解度和光褪色．结果表明共轭链上引入方酸桥环提高了光稳定性，Ｎ－烷基对染料的λｍａｘ的影响很小，但较大地改进了溶解度与熔点，带有支链的烷基有更好的溶解性能．
オeven squarylium indocyanine dyes with different Nalkyl group were synthesized. Their structures were confirmed by IR, 1H NMR, MS spectroscopy and element analysis. Absorption spectra, melting points, solubilities and photofading were also studied. It was found that introducing squaric bridge in conjugated chain improved photostabilities. Influence of Nalkyl groups on λmax were weak, but were great on solubilities and melting point. The group with branched chain on nitrogen atom having good solutilities was found.
