摘要:
A dyad bearing diarylethene and spiropyran units were synthesized. Ultraviolet light, visible light, H+, and Fe3+ inputs induce lethene with spiropyran form (3), the colored closed form of diary ethene with the multiple interconversion among the colorless diary spiropyran form (4), ME (5), MEH (6, 7) and MEH center dot Fe3+ (8). The efficient energy transfer from the anthracene emission to MEH center dot Fe3+ or ME center dot Fe3+ form was achieved. Using multi-mode photo switching in a dyad 3, logic gates may be built.
