| Summary: | 碩士 === 國立中正大學 === 化學暨生物化學研究所 === 99 === The novel metal-organic coordination polymers︰{[Zn2(bpe)2(TDC)2(H2O)]‧H2O}n (1), {[Zn(dpe)(TDC)]}n(2), {[Zn(bpe)0.5(TDC)(DMA)]}n (3), {[Zn2(dpe)2(TDC)2]‧DMSO}n (4), {Zn(bpp)(TDC)}n (5) and {[Cd0.5(TDC)]‧(CH3)2NH2‧H2O‧0.72DMA}n (6) (bpe = 1,2-bis(4-pyridyl)-ethane, dpe = 1,2-bis(4-pyridyl)-ethylene, bpp = 1,3-bis(4-pyridyl)-propane, H2TDC = Thiophene-2,5-dicarboxylic acid). All these compounds were structurally characterized by single-crystal and powder X-ray diffraction technique, in which complexes 3, 5 and 6 are 2D structures, and complexes 1, 2 and 4 are 3D structures. Their thermal stabilities and photoluminescence behaviors have also been investigated, in which complexes 1, 3 and 4 appear phase transformation after heating, and they are irreversible process.
