报道了一种多色可调、多态可切换的有机凝胶，它由聚集型增强发射的二茂铁有机凝胶剂和光致变色型二芳基乙烯染料组成。混合有机凝胶可以在四种不同的状态(蓝色发射凝胶、非发射溶胶、绿色发射凝胶和绿色发射溶胶)之间进行可逆切换，并通过热和光的组合进行调制。有趣的是，这种四状态切换构成了一个由两个激励输入和三个输出组成的组合逻辑电路。演示了该混合凝胶系统的可逆荧光写入、切换、擦除和图像图案化过程。
Multicolor tunable and multistate switchable organogel is reported, which consists of a cyanostilbene organogelator showing aggregation-induced enhanced emission and a turn-on type photochromic diarylethene dye. The mixed organogel can be reversibly switched among four different states (blue-emitting gel, nonemissive sol, green-emitting gel, and green-emitting sol) modulated by a combination of orthogonal stimuli of heat and light. It is interestingly noted that this four-state switching constitutes a combinational logic circuit consisting of two stimuli inputs and three outputs. Reversible fluorescence writing, switching, erasing, and image patterning processes on this mixture gel system are demonstrated.
