title: Novel phosphorescent hydrogels based on an Ir(III) metal complex.
abstract: Novel phosphorescent hydrogels have been explored by immobilizing an Ir(III) metal complex into the matrices of hydrogels. FTIR spectra demonstrate that the Ir(III) -PNaAMPS hydrogel is achieved by irreversible incorporation of positively charged [Ir(ppy)(2)(dmbpy)]Cl (ppy = 2-phenylpyrine, dmbpy = 4,4'-dimethyl-2,2'-bipyridine) into negatively charged poly(2-acrylamido-2-methylpropane sulfonic acid sodium) (PNaAMPS) hydrogel via electrostatic interaction. The photoluminescent spectra indicate that the Ir(III)-PNaAMPS hydrogel exhibits stable phosphorescence. In vitro cultivation of human retinal pigment epithelial cells demonstrates the cytocompatibility of the Ir(III)-PNaAMPS hydrogel. This work herein represents a facile pathway for fabrication of phosphorescent hydrogels.
