Abstract

New crystalline lanthanoid–metalloporphyrin porous frameworks [(Zn(H2O)–OCPP)Ln2(H2O)4Na2]n·solvent (Ln = Sm, Eu, Gd, Tb, and Dy) (LnMPF-1) were synthesized from an octatopic tetrakis-(3,5-dicarboxyphenyl)porphyrin building block through a synthetic approach using NaOH as a modulator to enhance the robustness of the metal–organic-framework (MOF) product and the formation of sizeable crystals. The formulated MOFs adopt a (4,8)-connected topology and are perforated by 1D tubular zigzag channels of about 1.5 nm in diameter. The frameworks possess permanent porosity and display appealing photophysical properties.
