Series of resorcin[4]arene-based lanthanide coordination polymers and selective luminescent sensing properties

Eight coordination polymers based on lanthanide ions and a tetracarboxylate-functionalized resorcin[4]arene ligand have been constructed. 1 and 2 exhibit high activities in detecting Fe3+, POMs, nitromethane and nitrobenzene by quenching effects. 2 could be employed as a turn-on-type luminescent sensor for N,N-dimethylformamide and N,N-dimethylacetamide.275
