This work presents the construction of a porous lead-organic framework (UPC-10) with large channels of ∼24 Å. UPC-10 shows efficient adsorption of I2 and selective adsorption of some dyes containing the SO3− group. After the adsorption of dyes, UPC-10 exhibits a CO2 gas uptake ability. Furthermore, UPC-10 could be transformed into PbS in a H2S atmosphere, and the derived PbS manifests N2 and CO2 uptake abilities. [ABSTRACT FROM AUTHOR]

Twoisomorphous lanthanide–organic frameworks, Ln(BDC)1.5(DMF)(H2O) (Ln = Er (1), Tm (2)) have been synthesized based on 1,4-benzenedicarboxylicacid (H2BDC). Because of the 2-fold interpenetration, thepores are partly blocked and there are no significant gas adsorptionsfor these two interpenetrating nets. Through control over interpenetrationby applying an organic ligand with hindrance groups or replacing coordinatedsolvent molecules with a chelating ligand, three non-interpenetratinglanthanide–organic frameworks, Er2(BDC)3(phen)2·3H2O (3), Tm(TBDC)1.5(DMF)(H2O)·2H2O (4), Er2(TBDC)3(phen)2·4DMF·2H2O (5), possessing the same topology with 1and 2, have been synthesized and characterized.Further changing reaction conditions, three other porous lanthanide–organicframeworks with different structures with 1–5, Tm(BDC)1.5(H2O)·0.5DMF·C2H5OH·2H2O (6), Tm4(BDC)6(H2O)2(DMF)(C2H5OH)·2DMF·2H2O (7),and Sm(TBDC)1.5(phen)(H2O)·DMF·H2O (8), have been constructed. Gas sorption measurementsfor 5, 6, 7, and 8have been carried out and revealed that these materials possesspermanent porosity. The catalytic property for complex 6has also been studied.
