Abstract

Abstract : A multi-addressable diarylethene was designed and synthesized, which not only acted as a fluorescent sensor for Al 3+ with high selectivity, but was also used to construct a combinational logic circuit. Abstract : A novel photochromic diarylethene with a naphthalofuran group was designed and synthesized, and its structure was determined by single-crystal X-ray diffraction analysis. Its multi-addressable properties were investigated using light stimulation and chemical agents. The diarylethene was highly sensitive to Al 3+ with obvious emission intensity and fluorescent color changes, indicating that it could act as a naked-eye fluorescent sensor for Al 3+ . Furthermore, a combinational logic circuit was constructed with the unimolecular platform using four input signals (In1: UV light; In2: visible light; In3: Al 3+ ; In4: DETA) and one output signal (fluorescence intensity at 536 nm).
