摘要

Based on the mixed ligands XN (4'-(4-pyridine)4,2':2',4"-terpyridine) and isophthalic acid (IPA),three new metal-organic frameworks (MOFs) {[M2(XN)2(IPA)2]·2H2O}n (M=Co (1),Mn (2),Ni (3)) were assembled and structurally characterized,presenting 3D pillar-chain feature structures.Stability measurements demonstrate that these compounds possess high thermostability and can endure different organic solvents as well as various acid/base solutions with pH range of 1 to 14.Importantly,compounds 1-3 can serve as high-efficiency catalysts for the transformation of CO2 and aziridines to form high-value oxazolidinones under mild conditions,exhibiting excellent cyclicity at least five times.
