摘要

A novel family of diarylethene (DTE)-phthalocyanine (Pc) dyad systems were designed and synthesized. It was found that the significant change in the extension of the linear n-conjugation of DTE when irra-diated by 254 nm UV light directly made the absorption of the Q-band of phthalocyanine decrease. De-tecting the absorption changes of the Q-band would not induce the reversible photochromic reaction. Therefore, non-destructive readout was feasible based on the spectral changes of the Q-band whensuch materials were used as storage media.
