A doubly interpenetrated metal-organic framework, Zn(3)(TATB)(2)(H(2)O)(2) (2), with chiral (10,3)-a topology, has been synthesized from an achiral, trigonal-planar ligand, 4,4',4″-s-triazine-2,4,6-triyltribenzoate (TATB). The large chiral channels in 2 act as scaffolds for the inclusion of N,N-dimethylaniline (DMA) molecules by donor-acceptor interactions. The resulting host-guest composite, DMA@2, shows desirably intense luminescence, which originated from photoinduced charge-transfer interactions in excited states.
一个具有手性(10,3)-a 拓扑结构的双重互穿金属有机骨架，Zn(3)(TATB)(2)(H(2)O)(2)（2），由非手性的三角平面配体 4,4',4″-均三嗪-2,4,6-三羧酸三苯酯（TATB）合成得到。2 中的大的手性通道作为包含 N,N-二甲基苯胺（DMA）分子的支架，通过供体-受体相互作用。所得的主客体复合材料 DMA@2 表现出令人满意的强发光，其源于激发态的光诱导电荷转移相互作用。
