| Abstract: | A thermally stable dysprosium porphyrin with a three-dimensional (3D) porous open framework, Dy(H2TPPS)]n? nH3O?2nH2O (1) (H2TPPS = tetra(4-sulfonatophenyl)porphyrin), has been synthesized via hydrothermal reactions and structurally analyzed by an X-ray single-crystal diffraction method. The 24-membered macrocyclic ring of H2TPPS is exactly coplanar and the center is free from metal. The dysprosium ion is coordinated by eight Osulfonic atoms from eight H2TPPS moieties, forming a distorted square anti-prism geometry. Complex 1 shows a void space of 210 Å3, occupying 9.06% of the unit-cell volume. The 3D porous open framework of 1 is thermally stable up to 380 °C. Complex 1 exhibits a red fluorescence emission with a quantum yield and lifetime of 2.7% and 136 μs, respectively. CV result reveals one reductive peak at ? 0.33 V and one quasi-reversible wave with E1/2 = ? 0.81 V. |
