报道了一种具有前所未有的hxg-d-4-Fddd拓扑结构的自链网状结构，即Zn(bdc)(L)·溶剂（1,L = N4，N4′-二（吡啶-4-基）联苯-4,4′-二甲酰胺，H2bdc =对苯二甲酸）。除去客体分子后，晶格不受影响，由此产生的永久孔隙可用于各种有机分子的气相色谱分离。此外，还观察到依赖于激发波长的显著可调光致发光和直接白光发射，以及可见光光催化活性，创造了一种新的多功能材料原型。
A 3-fold interpenetrating porous metal–organic framework, namely, Zn(bdc)(L)·solvents (1, L = N4,N4′-di(pyridin-4-yl)biphenyl-4,4′-dicarboxamide, H2bdc = terephthalic acid), composed of self-catenated nets with unprecedented hxg-d-4-Fddd topology is reported. Upon removal of guest molecules, the crystal lattice is unaffected, and the resulting permanent porosity can be applied for gas chromatography separation of various organic molecules. Furthermore, remarkable tunable photoluminescence and direct white emission dependent on excitation wavelength, as well as visible light photocatalytic activity, are also observed, creating a new multifunctional material antetype.
