合成了三个具有桥链的七甲川菁染料。研究染料结构对最大吸收波长的影响,并测定了染料在18种溶剂中的吸收光谱,发现染料的V_(max)~(ab)分别与溶剂的n~2-1/2n~2+1、(ε-n~2)(2ε+n~2)/ε(n+2)~2和((ε-1)/(ε+2))-((n~2-1)/(n~2+2))存在着良好的钱性关系。
Three chemitra cyanine dyes with a bridge were synthesized. The effect of the dye structure on the maximum absorption wavelength was studied. The absorption spectra of the dye in 18 solvents were determined. The results showed that the V_ (max) ~ (ab) of the dye were related to the n ~ 2-1 / 2n ~ (n-2) / (n + 2) ~ 2 and ((ε-1) / (ε + 2)) - ((n ~ 2-1) / (n ~ 2 + 2)) There is a good money relationship.
