| Abstract: | Three lanthanide complexes with the ligand 4‐sulfophthalate (sp3–), Ln(H2O)2(sp)]n Ln = Dy ( 1 ), Tb ( 2 ), and Er ( 3 )], were solvo‐/hydrothermally synthesized by changing the rare earth cations, and were characterized structurally and photophysically. Complexes 1 – 3 are isostructural, exhibiting a two‐dimensional layered structure with centrosymmetric dinuclear subunits infinitely extended by 4‐connected sp3– connectors. Photoluminescence spectra of 1 – 3 demonstrate that anionic sp3– ligand can serve as a functionalized chromophore to sensitize the luminescent emission of the lanthanide ion, suggesting that the sp3–‐involved lanthanide complexes can be used as novel optical materials. |
