Selective photoswitching of a dyad with diarylethene and spiropyran units

A dyad bearing diarylethene and spiropyran units were synthesized. Ultraviolet light, visible light, H +, and Fe 3+ inputs induce the multiple interconversion among the colorless diarylethene with spiropyran form ( 3 ), the colored closed form of diarylethene with spiropyran form ( 4 ), ME ( 5 ), ME...

Description
Summary:A dyad bearing diarylethene and spiropyran units were synthesized. Ultraviolet light, visible light, H +, and Fe 3+ inputs induce the multiple interconversion among the colorless diarylethene with spiropyran form ( 3 ), the colored closed form of diarylethene with spiropyran form ( 4 ), ME ( 5 ), MEH ( 6 , 7 ) and MEH·Fe 3+ ( 8 ). The efficient energy transfer from the anthracene emission to MEH·Fe 3+ or ME·Fe 3+ form was achieved. Using multi-mode photo switching in a dyad 3 , logic gates may be built. Graphical Abstract
