摘要：AbstractBiocompatible luminescent hydrogels containing covalently linked terbium complexes with a macrocyclic ligand are prepared by a facile method. The environmentally friendly preparation procedure is carried out at room temperature using water as a solvent. These new hybrid materials can act as luminescent sensors to detect Fe3+with relative selectivity and high sensitivity. The hydrogels also show pH sensing with a wide range.Alginate hydrogels containing covalently linked terbium complexesare prepared by a facile method. These luminescent hydrogels can be used as sensors to detect Fe3+ions and pH.
