Abstract
Fluorescence-based probes have received considerable attention because of their superiority in high selectivity and sensitivity. In this work, two novel luminescent isostructural coordination polymers (CPs), namely, [Zn3(HL)2(DMF)2(H2O)2]·2H2O (1) and [Cd3(HL)2(DMF)2(H2O)2]·2H2O (2), were successfully prepared by using a new resorcin[4]arene-based tetracarboxylic acid H4L under solvothermal conditions. In 1 and 2, HL3- anions bridge four metal cations to form charming 2D double layer structures. Drastically, the highly selective and sensitive luminescent detection of small organic molecules, metal cations and anions, particularly of Fe3+, Cr2O72- and nitrobenzene, has been studied using 1 or 2 as a promising luminescent sensor.
