【Abstract】 The special negative photochromic properties of dimethyldihydropyrene and its derivatives are introduced. The paper also discusses how the properties of optical and the switch change with the substituents, spacers and fused groups. The practical applications on photoswitches and photochemical readout of each state are reviewed and the future foreground of photochromic dimethyldihydropyrene are presented.更多还原
