Metallo‐Supramolecular Gels that are Photocleavable with Visible and Near‐Infrared Irradiation

A photolabile ruthenium‐based complex, [Ru(bpy)(2)(4AMP)(2)](PF(6))(2), (4AMP=4‐(aminomethyl)pyridine) is incorporated into polyurea organo‐ and hydrogels via the reactive amine moieties on the photocleavable 4AMP ligands. While showing long‐term stability in the dark, cleavage of the pyridine–ruthe...

description A photolabile ruthenium‐based complex, [Ru(bpy)(2)(4AMP)(2)](PF(6))(2), (4AMP=4‐(aminomethyl)pyridine) is incorporated into polyurea organo‐ and hydrogels via the reactive amine moieties on the photocleavable 4AMP ligands. While showing long‐term stability in the dark, cleavage of the pyridine–ruthenium bond upon irradiation with visible or near‐infrared irradiation (in a two‐photon process) leads to rapid de‐gelation of the supramolecular gels, thus enabling spatiotemporal micropatterning by photomasking or pulsed NIR‐laser irradiation
