Abstract
A terbium-zinc porphyrin, i.e. [TbZn(TPPS)H3O]n (1) (TPPS=tetra(4-sulfonatophenyl)porphyrin), has been obtained from a solvothermal reaction and structurally analyzed by single-crystal X-ray diffraction. Compound 1 is characteristic of a condensed three-dimensional (3-D) porous open framework with two types of infinite one-dimensional (1-D) chain-like structure. Compound 1 exhibits a void space of 215Å3, which is 9.2% of the unit-cell volume. TG/DTA measurement reveals that the framework of compound 1 is thermally stable up to 336°C. In order to reveal its photophysical and electrochemical properties, we investigated compound 1 in detail with UV–vis spectra, fluorescence, quantum yield, luminescence lifetime, and CV/DPV.
