Abstract:

A chiral camphor derivative, D-4-(3-carboxy-2,2,3-trimethylcyclopentanecarboxamido)benzoic acid (D-H2ctba) was designed and synthesized by simple organic reaction. Then, a self-assembly reaction occurred between D-H2 ctba and cadmium(Ⅱ) nitrate, [Cd3(ctba)3·H2O]n(1) was obtained and characte-rized by single-crystal X-ray diffraction(XRD), powder X-ray diffraction(PXRD), elemental analysis, thermogravimetric analysis(TGA) and circular dichroism(CD) measurement. Single-crystal structure analysis of compound 1 reveals that it crystallizes in the chiral orthorhombic space group P21212 and shows a 3D chiral structure. Compound 1 exhibits a kind of metal-carboxylate cluster which contents six octahedral Cd(II) centers and twelve carboxyl groups. Meanwhile the metal-carboxylate clusters are joined together by carboxyl to form infinite(—Cd—O—C—) rods, and these rods consist the rod-shaped secondary building units(SBUs). The rod-shaped SBUs are stacked in parallel and connected by the ctba ligand to give 3D framework. Additionally, the luminescent spectrum of compound 1 shows a strong fluorescence at room temperature.
