A new rigid ligand anthraquinone-1,4,5,8-tetracarboxylic acid (H4AQTC) and its two new porous metal-organic frameworks: Syntheses, structures and properties

A new rigid multicarboxylates anthraquinone-1,4,5,8-tetracarboxylic acid (H4AQTC) was synthesized based on a modified synthetic procedure from 2,5-dimethylfuran and maleic anhydride. This rigid ligand can be widely utilized to construct rigid porous MOFs which may be candidates of porous materials. Two new rigid porous MOFs {[Cd(AQTC)0.5(H2O)3]·H2O}n(1) and {[Ni(AQTC)0.5(BPY)0.5(H2O)3]·2H2O}n(2) based on this rigid ligand are reported (BPY = 4,4'-bpy). The adsorption properties of complexes 1 and 2 are investigated, and the Langmuir surface areas are measured to be 43.25 m2/g and 389.14 m2/g.
