| By using 2,8,14,20-tetra-pentyl-6,12,18,24-tetra-methoxy-4,10,16,22-tetra-carboxymethoxy-resorcin[4]arene（H4L）,eight lanthanide-based coordination polymers（CPs）,[T b（H L）（D M F）（H 2 O）2]·3 H 2 O（1）,[E u（H L）（D M F）（H 2 O）2]·3 H 2 O（2）,[G d（H L）（D M F）（H 2 O）2]·3 H 2 O（3）,[Y b（H L）（D M F）（H 2 O）2]·3 H 2 O（4）,[Sm（HL）（DMF）（H2O）2]·3H2O（5）,[Ce（HL）（DMF）（H2O）]（6）,[Pr（HL）（DMF）（H2O）]（7）and[La（HL）（DMF）（H2O）]（8）,have been constructed.Isostructural CPs 1-5 exhibit charming ribbons built with rare earth cations and cup-like HL3-anions.The ribbons are further extended by hydrogen bonds to form supramolecular layers,respectively.CPs 6-8 are isostructural and show unique layer networks.The CPs were characterized by IR and powder X-ray diffraction.The solid fluorescence properties of 1 and 2 were studied.The fluorescence detection of CPs 1 and 2 towards metal cations,polyoxometalates（POMs）and organic small molecules by quenching and turn-on process has been systematically investigated. |
