Suspensions of organic microcrystals produced in the presence of polymers : diversity of UV/Vis absorption and fluorescence properties according to the preparation conditions
Free-standing microcrystals of an organic fluorescent dye, specifically, 4-n-octylamino-7-nitrobenz-2-oxa-1,3-diazole, were prepared using a solvent-exchange process at room temperature, in the presence of polymers used as additives. Parameters such as the dye concentration, the nature and concentra...
