Abstract

New hetero aggregates where different dyes stacked alternately were prepared by hybridizing two DNAs, each of which tethered a different dye in the centre of strand. Spectral changes due to exciton coupling between different kinds of dyes were observed. Especially, hetero aggregates of Methyl Red and 2- nitro-4'-dimethylaminoazobenzene showed substantial narrowing of the band, demonstrating coherent coupling occurred in these aggregates.

摘要

通过杂交两条DNA制备了不同染料交替堆积的新型杂聚集体，每条DNA在链的中心连接一种不同的染料。观察到了由于不同种类染料之间的激子耦合引起的光谱变化。特别是，甲基红和2-硝基-4'-二甲基氨基偶氮苯的杂聚集体显示出谱带明显变窄，表明这些聚集体中发生了相干耦合。
