Thiolate-based One-dimensional Flexible Pb–MOFs Exhibiting a Large Sorption Hysteresis Phenomenon

Abstract
A novel thiolate-based Pb-metal-organic framework, [Pb2(Hdtd)4·2DMSO]n (KGF-2·DMSO, H2dtd = 6-dibutylamino-1,3,5-triazine-2,4-dithol and DMSO = dimethyl sulfoxide) was prepared. The crystal structure of KGF-2·DMSO consists of a one-dimensional chain composed of Pb ions and surrounding ligands. Following removal of the guest DMSO molecules, KGF-2 was obtained as a crystalline powder, which exhibited selective water sorption properties.
