Two novel metal-organic frameworks, [Cd(Bna)(DMF)2(H 2O)2] n · nDMF (I) (Bna = 2,2′-dihydroxy-l,l′-dinaphthyl-3,3′-dicarboxylate) and [Cd(Bna)(Bipy)(DMF)2] n (II) (Bipy = 4,4′- bipyridine) have been synthesized under mild conditions and structurally characterized. Crystal structural analyses reveal that complex I adots a 1D spiral structure with DMF guest molecules in the spiral by hydrogen bondings. Complex II is constructed by -Cd-Bna-Cd- zigzag chains, which are further connected by Bipy into a 2D sheet. X-ray powder diffraction and thermogravimetric analyses for I and II show that they are highly themally stable in the solid state.

Chiral discrimination of α-amino acids has been realized by a C 2-symmetric homoditopic receptor, which is based on a binaphthyl chiral skeleton with 2,2′diisopropoxy substituents and a common binding side arm, (o-carboxamido)-trifluoroacetophe
