Preparation of coherent hetero clusters with threoninol scaffold.
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.
