A luminescent metal–organic framework, [Cd(HDMPhIDC)(H2O)]n (1), has been successfully synthesized and structurally characterized. MOF 1 exhibits good recognition performance for Fe3+ ions. The recognition mechanism of Fe3+ was explored by UV-Vis and PXRD determinations. 1 was found to have a high proton conductivity value of 1.30 × 10−4 S cm−1 at 100 °C and 98% RH.
