True colors: Novel pyrene analogues of Prodan exhibit outstanding photophysical properties with remarkably high fluorescence quantum yield (QY) in solvents ranging from apolar hexane to polar methanol (see figure). This is accompanied by strong solvatochromism and large Stokes shifts. These properties have not been previously achieved in enormous solvatochromic dyes, but are quite useful for emitting materials and imaging tools.
普罗布胺的新型苝类类似物在从非极性己烷到极性甲醇的溶剂中表现出出色的光物理性质，荧光量子产率（QY）非常高（见图）。这伴随着强溶剂化变色和大斯托克斯位移。这些性质以前在巨大的溶剂化变色染料中没有实现，但对于发射材料和成像工具非常有用。
