Microcrystals of a fluorescent dye, 4-n-octylamino-7-nitrobenzoxadiazole, were prepared by thereprecipitation method. Poly(amidoamine)dendrimers bearing anionic, cationic or neutral terminating groupswere used as additives in the recrystallization medium. They directed the formation of thin plates or spindlelikemicrocrystals. The UV/vis absorption and emission properties were investigated on the microcrystalsuspensions
