Preparation of "comb-type" hetero aggregates by DNA-dye conjugation.
New alternating hetero aggregates ((")comb-type(") hetero aggregates) were successfully prepared by hybridizing two single-stranded DNAs, each of which tethered different homo-dye aggregates in the centre of the strand. When excitonically inert dyes (Methyl Red and azobenzene) were alternately assembled, broadening of the spectrum was observed. On the other hand, alternating aggregates of Methyl Red and Naphthyl Red showed substantial narrowing of the band. Although the peak maxima of these two dyes were different, strong exciton coupling occurred.
