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 (I₆₀₄) 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.

成功设计并合成了一种新型的可见光控制的光致变色荧光DASA（供体-受体Stenhouse加合物）开关。通过结合使用1,8-萘二甲酰亚胺荧光团和基于二氢吲哚的“供体”和巴比妥酸“受体”，DASA分子在440 nm和616 nm处显示两个独立的吸收带。已经在不同溶剂中研究了荧光供体-受体Stenhouse加合物（DASA-NDI ）的物理和热力学性质。根据在可见光/热和H ⁺ / Cu ²⁺下的独特荧光特性，使用604 nm（I ₆₀₄）的荧光强度作为输出以及可见光H ⁺和Cu ²⁺ 作为输入，可以描述和操作由NOR和AND逻辑组成的组合逻辑门。
