Abstract
The homochiral coordination polymers of zinc(II) with D-camphoric acid (D-H2Cam) as bridges and 4′-p-tolyl-2,2′:6′,2″-terpyridine (ttpy) and 1,10-phenanthroline (phen) as accessorial terminal ligands, namely [Zn2(D-Cam)2(ttpy)2]n (I1) and [Zn2(D-Cam)2(phen)2]n (I2), have been synthesized and characterized by elemental analysis, IR, PXRD, and X-ray diffraction analysis. Both complexes have 1D homochiral coordination chains bridged by D-Cam. Interestingly, the coordination numbers of ZnII ions, the coordination modes of D-Cam, and the crystal structures in I1 and I2 vary with the accessorial ligands ttpy and phen used. Additionally, compounds I1 and I2 have stronger fluorescence and higher thermostability, indicating their potential utility in photoluminescent materials.
