ABSTRACT
A new metal-organic framework of [Cu2(L)(H2O)2]·2DMF (1) (H4L = quaterphenyl-3,3′″,5,5′″-tetracarboxylic acid) has been prepared and characterized. It has the NbO-derived topology that was observed in MOF-505. Magnetic study reveals the overall antiferromagnetic interactions between neighboring Cu(II) ions in compound 1. In addition, we performed an optimization by semiempirical PM5 method simulations to investigate the loading of 5-FU to 1 at the molecular level.
