The development of tunable molecule separation membranes requires materials with remote controllability and ultra-high separation capability. In this paper, a novel photoswitchable metal organic framework (MOF) thin film (Cu(AzoBPDC)) was prepared by liquid phase epitaxial layer-by-layer assembly to realize the reversible remote-controlled switching. The azobenzene side groups in the Cu(AzoBPDC) thin film showed excellent reversible photoswitching performance under UV (365 nm) and Vis (450 nm) irradiation, achieving the remote-controlled mode of the diffusion flux of polar gas molecules in the MOF thin film.
可调谐分子分离膜的发展需要具有远程可控性和超高分离能力的材料。本文通过液相外延层层组装制备了一种新型光致变色金属有机骨架（MOF）薄膜（Cu(AzoBPDC)），实现了可逆远程控制开关。Cu(AzoBPDC)薄膜中的偶氮苯侧基在紫外光（365nm）和可见光（450nm）辐照下表现出优异的可逆光致变色性能，实现了MOF 薄膜中极性气体分子扩散通量的远程控制模式。
