真实色彩：Prodan的新型芘类似物在从非极性己烷到极性甲醇的溶剂中表现出突出的物理化学性质，具有非常高的荧光量子产率（QY）（见图）。这是伴随着强烈的溶致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，但对于发光材料和成像工具非常有用。
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.
