摘要：A novel photochromic fluorescent DASA (donor-acceptor Stenhouse adduct) switch controlled by visible light was successfully designed and synthesized. Using 1,8-naphthalimide fluorophore in combination with indoline-based "donor" and barbituric acid "acceptor", the DASA molecule exhibits two independent absorption bands at 440 nm and 616 nm. The physical and thermodynamic properties of fluorescent donor-acceptor Stenhouse adduct (DASA-NDI) have been investigated in different solvents. In accordance with the unique fluorescent properties under visible light/heat and H+/Cu2+, using fluorescence intensity at 604 nm (I-604) as an output and visible light, H+ and Cu2+ as inputs, a combinatorial logic gate consisting of NOR and AND logics can be described and operated.
