摘要：Proton conduction controlled by light is important for advanced applications in sensors and information processing *** herein report a metal-organic framework(MOF)thin film by introducing indocyanine green dye into HSB-W5(HSB=hydrogenated Schiff base)matrix(ICG@HSB-W5)to construct a series of basic logic gates(NOT,NAND,and NOR)on account of its good photothermal conversion ability and photo-controlled proton *** proton conductivity of ICG@HSB-W5 thin film is 25 times higher than that of the pristine HSB-W5 thin film and responses efficiently to *** addition,the change of proton conductivity is very large with an ON/OFF ratio above1000 and enough to be distinguished to build logic *** this logic gate system,808-and 405-nm lasers are used as inputs and the proton conductivity is used as output signal with different *** electrical output signal is convenient and available to be received and *** offers a new route for the design of molecular logic gates based on MOF and facilitates the construction of proton-based logic gate or more complicated logic devices.
