In this study, metal halide perovskites, which are excellent materials for optoelectronic devices, were examined to construct molecular logic gates. The photoluminescence (PL) and electrochemiluminescence (ECL) properties of the CsPbBr3 nanocrystals (NCs) effectively maintained in CsPbBr3@SiO2 NC films; these films simply prepared by depositing on electrode surface through viscosity SiO2 coating. dual-optical signals found have different responses external stimuli Fe(III) dopamine (DA). PL signal was quenched Fe(III), effect exacerbated at a high concentration DA due formation oxidation products. However, addition ascorbic acid (AA) could restore signal. While ECL did not show evident changes with low be reverted Fe(III). Thus, multiple input–output circuit based film system constructed using DA, AA as 3 inputs states 6 outputs. A series circuits, including an encoder/decoder, dual transfer gate, parity checker, demultiplexer, resettable keypad lock, successfully simulated. Specifically, ternary CONSENSUS gate output initially mimicked electrode. This work provide simple approach design information modulated multioptical perovskites further expand potential applications multiple-molecule recognition, chemical storage, devices.
