光控制的质子传导对于传感器和信息处理设备的先进应用具有重要意义。本文报道了一种金属-有机骨架(MOF)薄膜，它具有良好的光热转换能力和光控质子导电性，通过在HSB-W5(HSB=氢化希夫碱)基质(ICG@HSB-W5)中引入吲哚青绿染料来构建一系列基本逻辑门(NOT、NAND和NOR)。ICG@HSB-W5薄膜的质子电导率是原始HSB-W5薄膜的25倍，对激光有很高的响应能力。此外，质子电导率的变化非常大，通断比在1000以上，足以区分开建立逻辑门。在该逻辑门系统中，808 nm和405 nm激光作为输入，质子电导率作为不同阈值的输出信号。电输出信号方便，便于接收和检测。它为基于MOF的分子逻辑门的设计提供了一条新的途径，并为基于质子的逻辑门或更复杂的逻辑器件的构建提供了便利。
Proton conduction controlled by light is important for advanced applications in sensors and information processing devices. We 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 conductivity. The 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 lasers. In addition, the change of proton conductivity is very large with an ON/OFF ratio above 1000 and enough to be distinguished to build logic gates. In this logic gate system, 808- and 405-nm lasers are used as inputs and the proton conductivity is used as output signal with different thresholds. The electrical output signal is convenient and available to be received and detected. It 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.
