Kurzfassung englisch:
A photolabile ruthenium-based complex
[Ru(bpy)2(4AMP)2](PF6)2 is presented. The metal centre was
incorporated into polyurea organo and hydrogels via the reactive amine moieties on the photocleavable 4-(aminomethyl)pyridine (4AMP) ligands. While showing long-term stability in the dark, cleavage of the pyridine-ruthenium bond upon irradiation with visible and near infrared irradiation (in a two-photon process) leads to rapid degelation of the supramolecular gels, thus enabling spatiotemporal micropatterning by photomasking or pulsed NIR-laser irradiation.
