摘要
以缩合剂２氯１甲酰基３羟亚甲基环己烯、２亚甲基１，３，３三甲基吲哚啉和碘化钾等为原料，通过在缩合的同时进行吲哚啉的季胺化反应，以６２．５％的收率合成了１，３，３，１’，３’，３’六甲基１１氯１０，１２亚丙基三碳菁红外染料，并采用熔点测定、元素分析、ＩＲ及１ＨＮＭＲ分析确证了产物的结构。该染料的电子吸收光谱表明，它的最大吸收波长为７７４ｎｍ，最大摩尔消光系数为２．７×１０５Ｌ·ｍｏｌ－１·ｃｍ－１。该染料易溶于二氯甲烷、三氯甲烷、乙腈和醇类等溶剂中。
An infrared dye,1,3,3,1',3',3'hexamethyl11chloro10,12propylenetricarbocyanine iodide,has been synthesized by condensation of 2methylene1,3,3trimethylindolenine,2chloro1formyl3hydroxy methylenecyclohexene and potassium iodide in 62.5% yield.The structure was identified by elementary analysis,IR and 1 HNMR.The electron absorption spectrum of it shows that the maximum absorption max is at 774 nm with max of 2.7105Lmol-1cm-1.The dye can be easily dissolved in dichloromethane,chloroform,acetonitrile and alcohol.
