%X A novel diarylethene with a triazole-linked
rhodamine B unit has
been synthesized by click chemistry. When triggered by light, proton,
and metal ions, the diarylethene can be used as a fluorescence switch,
leading to a multiaddressable system. The diarylethene shows sequence-dependent
responses through efficient interaction of the specific triazole-linked
rhodamine B unit with proton and metal ions. Furthermore, the diarylethene
can serve as a naked-eye chemosensor for highly selective recognition
of different metal ions in different solvent systems. The diarylethene
was highly selective toward Al3+ with remarkable fluorescence
change from dark to yellow in acetonitrile, while it selectively recognized
Cu2+ with significant fluorescence change from dark to
bright yellow in the mixture of acetonitrile and water (v/v = 4/6).
Finally, a logic circuit was constructed with the unimolecular platform
by using the combinational stimuli of light and chemical species as
inputs and the fluorescence intensity at 595 nm as output.
