ABSTRACT One‐dimensional coordination polymer La‐CP , {[La(H 2 O) (HL O ) (L )]·H O} n containing a new luminescent ligand 4,7‐di(4‐carboxypyrazol‐1‐yl)‐2,1,3‐benzoxadiazole (H L was synthesized. Upon excitation at 400 nm, the compound shows strong emission with maximum 550 nm high photoluminescence quantum yield of 43%. demonstrates sensing properties toward aluminum and gallium cations, as well dihydrogen phosphate sulfate anions through enhancement response. The limits detection were 0.42, 0.70, 0.37, 0.40 μM, respectively. is first example sensor for anion among all types polymers. uptake analytes under conditions evaluated, absorption result such proposed probable response mechanism.
