title: A multiaddressable photochromic bisthienylethene with sequence-dependent responses: construction of an INHIBIT logic gate and a keypad lock.
abstract: A photochromic bisthienylethene derivative (BIT) containing two imidazole units has been synthesized and fully characterized. When triggered by chemical ions (Ag(+)), protons, and light, BIT can behave as an absorbance switch, leading to a multiaddressable system. BIT exhibits sequence-dependent responses via efficient interaction of the specific imidazole unit with protons and Ag(+). Furthermore, an INHIBIT logic gate and a keypad lock with three inputs are constructed with the unimolecular platform by employing an absorption mode at different wavelengths as outputs on the basis of an appropriate combination of chemical and photonic stimuli.
