摘　　要：Recently we have reported our study on the J-aggregate formation of an anionic cyanine promoted by the counterions of added salts under environmental conditions. The result showed that the counterions are bound to the dye ion J-stacks in 'stoichiometric' relation. Concerning the fact that polyeletrolytes could promote the formation of J-aggregate of cyanine dye ions, the authors suggested that the J-aggregates of an ionic cyanine might more easily induce the J-aggregation of other cyanine ions with opposite charges. The two
