Abstract

A green-chemical route using water/acetic acid as the solvent/modulator is proposed for obtaining the [Zr₆(µ₃-O)₄(µ₃-OH)₄(ADC)₆] MOF at 85 °C (Zr-HHUD-1; a UiO-66 analog with a face-centered cubic fcu topology, where ADC = acetylenedicarboxylate) and the alternative novel [Zr₆(µ₃-O)₄(µ₃-OH)₄(OH)₃(ADC)₄(H₃CCOO)(H₂O)₃] MOF at room temperature (Zr-HHUD-7; body-centered cubic bcu topology). Zr-HHUD-7 possesses two differently sized decorated pores, demonstrating higher IAST selectivity for CO₂ over CH₄ adsorption compared to Zr-HHUD-1. The temperature of synthesis is thus disclosed to control the degree of {Zr₆}-cluster connectivity, thereby enabling the tuning of the topology and sorption properties of zirconium-based metal-organic frameworks.

绿色水合成乙炔二羧酸锆mof的温度定向拓扑控制。

提出了一种以水/乙酸为溶剂/调制剂的绿色化学途径，可在85℃条件下获得[Zr6（µ3- o）4（µ3-OH）4（µ3-OH）4(ADC)6] MOF （Zr-HHUD-1；一种具有面心立方fcu拓扑的uuo -66模拟物，其中ADC =乙基二羧酸酯）和室温条件下的替代新型[Zr6（µ3- o）4（µ3-OH）4(ADC) 4(H2O)3] MOF （Zr-HHUD-7；体心立方bcu拓扑）。Zr-HHUD-7具有两个不同大小的装饰孔，与Zr-HHUD-1相比，对CO2的IAST选择性更高。因此，揭示了合成温度可以控制{Zr6}簇连通性的程度，从而可以调整锆基金属有机骨架的拓扑结构和吸附性能。
