We describe the synthesis and characterization of C2 symmetrical double chromophores, in which two identical chromophores are linked through ethylene glycol spacers of increasing lengths. The complexation ability of the trans stereopure form for each diastereoisomeric pair showed how the two chromophores, when the spacer unit is comprised of a diethylene or a triethylene glycol moiety, are able to interact in a positive way, stabilizing the resulting complexes when compared with single chromophore analogous compounds.
我们描述了C2对称双发色团的合成和特性,其中两个相同的发色团通过长度不断增加的
乙二醇间隔物连接。对于每个非对映异构体对,反式立体纯形式的络合能力表明,当间隔单元由
二乙二醇或
三乙二醇部分组成时,两个发色团能够以积极的方式相互作用,与单发色团类似化合物相比,稳定了所得络合物。
