Abstract
J-aggregated microcrystals of 1,1'-diethyl-2,2'-cyanine bromide [pseud oisocyanine bromide (PIC)] was prepared by salting-out in saturated po tasium bromide aqueous solution, reprecipitation in hexane and recryst allization in polymers at room temperature. J-band of microcrystals fr om aqueous conditions was sharp and blue-shifted compared with those f rom hydrophobic conditions. The size of the former microcrystals was s maller than that of the latter ones.
