Based on a flexible ether-oxygen tricarboxylate ligand, H3L = 3,5-bis[(3-carboxylphenyl)oxy]benzoic acid, one novel 2-D La-CP with the formula of {[La(L)(H2O)3]·H2O}n has been solventhermally synthesized. The 2-D bilayer structure of La-CP is constructed by carboxylate-bridged Lan(CO2)n layers connected by M-shaped tricarboxylate ligands arranged below and above, respectively. The La-CP exhibits blue luminescence and demonstrates multi-responsive luminescence sensing activities toward Fe3+, Cr(VI) and benzothiazoles (BTs) through luminescence quenching. It could be repeated after at least five cycling runs. The fast response, high sensitivity and selectivity makes it a potential multi-functional chemosensor.
