Abstract

Three metal-organic frameworks, {[Mg₂(MFDA)₂(DMF)₃]·0.5H₂O}_n (1), {[Ca(MFDA)(DMF)(H₂O)]·0.5DMF}_n (2) and [Ca(MFDA)(DMF)₂]_n (3) (DMF=N,N-dimethylformamide) have been synthesized by the solvothermal reactions between the ligand 9,9-dimethylfluorene-2,7-dicarboxylic acid (H2MFDA) and the corresponding metal salts, respectively. The single crystal X-ray structural analyses reveal that compounds 1–3 display three-dimensional structures based on the M(II)–O–C chains. It is interesting that the MFDA ligands in 1–3 have different dihedral angles between the two carboxylate groups ranging from 9.9(1)° to 41.8(2)°. All of compounds exhibit strong ligand-centered blue emissions under UV lights. Their thermal properties have also been studied.
