A first new porous d–p HMOF material with multiple active sites for excellent CO₂capture and catalysis

In this work, a new monometallic metal-organic framework (MOF), namely {[Pb2(L)2(H2O)]·H2O}n (1), was prepared via a N,O-mixed 2-(imidazol-1-yl)terephthalic acid (H2L) ligand and Pb(ii) ions. Then, a first new porous d-p heterometallic MOF (HMOF), namely {[PbZn(L)2]·DMA·H2O}n (2), was yielded via Zn(ii) ions and MOF 1 as the precursor because of the different coordination affinity of oxygen and nitrogen atoms with various metal ions. MOF 1 is a...
