There is an increasing demand for the development of lanthanide metal-organic frameworks and derived multifunctional materials. The functional properties such compounds are influenced by arrangement various Lewis basic sites or structural configurations ligands. In this study, a series isostructural Ln-MOFs containing phosphine-dicarboxylate ligand, [Ln(HL)(L)(DMF)]·DMF (where H2L = 5-(diphenylphosphanyl)isophthalic acid, Ln Tb3+ (1), Eu3+ (2), Gd3+ (3), Ce3+ (4), Nd3+ (5)), was synthesized under solvothermal conditions characterized in detail. Among obtained compounds, Tb-MOF 1 demonstrated excellent luminescent with high quantum yield (90.45%) considerable lifetime (1266 μs). Furthermore, acts as unique sensor 4-formylphenylboronic acid 9-[3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]carbazole, exhibiting low detection limits 1.38 3.62 mM, respectively. Additionally, Nd-MOF 5 efficient catalyst coupling carbon dioxide to epoxy resulting conversion rates (up 96%). This study further extends growing family provides insights preparing materials through modification organic ligands specific groups.
