A dysprosium‐zinc porphyrin, [DyZn(TPPS)H 3 O] n (1) (TPPS = tetra(4‐sulfonatophenyl)porphyrin), was prepared through solvothermal reactions and structurally characterized by single‐crystal X‐ray diffraction analyses. Complex 1 features a three‐dimensional (3‐D) porous open framework that is thermally stable up to 400 °C. Complex 1 displays a void space of 215 Å 3 , occupying 9.2% of the unit cell volume. The fluorescence spectra reveal that it shows an emission band in the red region. The fluorescence lifetime is 39 µsec and the quantum yield is 1.7%. The cyclic voltammetry (CV) measurement revealed one quasi‐reversible wave with E 1/2 = 0.30 V. Copyright © 2015 John Wiley & Sons, Ltd.
