| Popis: | Two lanthanide metal-organic frameworks (LOFs), namely, {[Tb(L3−) (H2O)]·3CH3CN}n (1) and {(Me2NH2+)0.5·[Gd(L3−)(HCOO−)0.5 H2O]·DMF·4EtOH·H2O}n (2) have been constructed by tris(4-carboxyphenyl)phosphane oxide (H3L) under solvothermal conditions. Structural analyses indicate that complex 1 appears a 3D 6-connected {412∙63} net based on the binuclear {Tb2(COO)2} clusters. Complex 2 is also a 3D framework. Furthermore, the photoluminescence of 1 in the solid state and different solvent emulsions were studied, the results indicate that 1 shows characteristic green emission of Tb3+ ion and has better fluorescent recognition for sorts of organic solvent molecules and Fe3+ ion. Finally, the result of the variable-temperature magnetic susceptibilities suggests that complex 2 have antiferromagnetic behavior between Gd(III) ions. |
