从配体的预设构型来看，三唑的引入不仅有利于提供富氮位点，而且有利于提高MOF材料的稳定性。在溶剂热条件下，采用两种相似的双功能三唑酸羧酸盐有机配体，成功构建了两种新型自互穿铜基金属有机骨架，它们具有非常相似的孔洞，但孔洞形状不同。此外，粉末x射线衍射、热重、气体吸附研究和理论计算揭示了它们不同的骨架稳定性和孔隙环境。
From the perspective of preset configuration of ligands, the introduction of triazole would be not only conducive to furnish sites rich in nitrogen, but also favorable to enhance the stability of MOF materials. Through employing two similar bifunctional triazolate–carboxylate organic ligands, two novel self-interpenetrating copper(II)-based metal–organic frameworks have been successfully constructed under solvothermal conditions, which exhibit very similar voids but different hole shapes. In addition, powder X-ray diffraction, thermogravimetry, gas sorption studies, and theoretical calculations reveal their different framework stabilities and pore environment.
