Photo-driven molecular switch based on the photochromism and solvatochromism of diarylethene dialdehyde

【摘要】 The two distinct characters of diarylethene dialdehyde derivative-photochromism and solvatochrom- ism are displayed in particular circumstances. The fluorescence of phosphorus (III) tetrabenzotri- azacorrole can be reversibly regulated by the three kinds of status of the diarylethene dialdehyde, col- orless ring-opened form, red ring-closed form, and blue ring-closed form, which is gated by visible light, ultraviolet light and ethanol individually or jointly. Based on this effect, a novel molecular INH logic switch is proposed.更多还原
