Molecule-based crystalline materials with angle-dependent polarized emission have attracted considerable attention owing to their extensive applications in displays and anticounterfeiting. Herein, one anionic metal-organic framework (MOF) {Zn(μ-OH)(NDC)(HNDC)} was constructed on the basis of an excellent photoactive ligand naphthalene-1,4-dicarboxylic acid (HNDC). The protonated 2-propylimidazole (HPIM) guests residing in the nanochannels of MOF can be exchanged by a D-π-A cationic dye. The resulted host-guest system shows a rare example of ratiometric fluorescent polarizations and highly enhanced photoelectron performance in comparison with the pristine MOF.
基于分子的具有角度依赖性偏振发射的晶体材料因其在显示和防伪方面的广泛应用而备受关注。在此，基于优异的光活性配体萘-1,4-二羧酸（HNDC）构建了一种阴离子金属有机框架（MOF）{Zn(μ-OH)(NDC)(HNDC)}。驻留在MOF纳米通道中的质子化2-丙基咪唑（HPIM）客体可被一种D-π-A阳离子染料交换。与原始MOF相比，所得的主客体系统展示了一个罕见的比例荧光偏振示例以及高度增强的光电子性能。
