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