However, the fundamental understanding of the characteristics of PLMOCs and metal ion sensing is still lacking. We report the synthesis of a series of Ag(bpy)(DA) PLMOCs (DA = dicarboxylic acids) and unravel key factors of the Ag-based PLMOCs regarding sensitivity in metal ion detection. The DA linkers with strong electron-donating groups (-NH2 and -OH) resulted in a red-shift in the PL emission of the Ag-based PLMOCs. Ag(bpy)(DA), displaying emission peaks in the UV region, showed higher sensitivity for Fe3+ compared to Ag-based PLMOCs with the emission peaks located in the vis region. Moreover, Ag(bpy)(DA) comprised of DA linkers with an amine group could exhibit sensitive detection toward Pb2+ ? The Royal Society of Chemistry. |
