Abstract
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.
