The development of new metal-organic frameworks (MOFs) thin films is important for expanding their functions and applications. Herein, we first report a new kind of MOF thin film by using aggregation-induced emission (AIE) dicarboxyl ligand through a liquid-phase epitaxial (LPE) layer-by-layer (LBL) spraying method (named AIE surface-coordinated metal-organic frameworks thin film, AIE-SURMOF). The obtained AIE-SURMOF ZnO(TPE) (ZnTPE) has highly growth orientation and homogeneous thin film, showing strong fluorescent property. Furthermore, by loading chiral guest in the MOF pore, the formed chiral encapsulated AIE-SURMOF can clearly indicate obvious circularly polarized luminescence performance with g of 0.01. This study provides new MOF thin film and new strategy for expanding function and application of MOF materials.
新型金属有机框架（MOF）薄膜的开发对于拓展其功能和应用至关重要。在此，我们首次通过液相外延（LPE）逐层（LBL）喷涂法，使用聚集诱导发光（AIE）二羧酸配体报道了一种新型MOF薄膜（命名为AIE表面配位金属有机框架薄膜，AIE-SURMOF）。所制备的AIE-SURMOF ZnO(TPE)（ZnTPE）具有高度的生长取向和均匀的薄膜，表现出强荧光特性。此外，通过在MOF孔中负载手性客体，形成的手性封装AIE-SURMOF能够清晰地显示出g值为0.01的明显圆偏振发光性能。本研究为拓展MOF材料的功能和应用提供了新型MOF薄膜和新策略。
