Two Self-Interpenetrating Copper(II)-Paddlewheel Metal-Organic Frameworks Constructed from Bifunctional Triazolate-Carboxylate Linkers

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 carbox-ylate 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.
