Light‐Operated Diverse Logic Gates Enabled by Modulating Time‐Dependent Fluorescence of Dissipative Self‐Assemblies

Abstract Light‐fueled dissipative self‐assembly possesses enormous potential in the field of optical information due to controllable time‐dependent optical signals, but remains a great challenge for constructing intelligent light‐operated logic circuits due to the limited availability of optical signal inputs and outputs. Herein, a series of light‐fueled dissipative self‐assembly systems with variable optical signals are reported to realize diverse logic gates by modulating time‐dependent fluorescence variations of the loaded fluorophores. Three kinds of alkyl trimethylammonium homologs are employed to co‐assemble with a merocyanine‐based photoinduced amphiphile separately to construct a series of dissipative self‐assemblies, showing unexpectedly different fluorescence control behaviors of loaded fluorophores during light irradiation and thermal relaxation processes. The opposite monotonicity of time‐dependent emission intensity is achieved just by changing the excitation wavelength. Furthermore, by varying the types of trimethylammoniums and excitation wavelengths, a robust logic system is accomplished, integrating AND, XNOR, and XOR functions, which provides an effective pathway for advancing information transmission applications.
