Subsequent in situ repair by persulfate enabled catalyst reactivation, but so far at the cost of decreasing catalytic activity over several repair cycles. We now show that tailored polyampholytic graft copolymers enable electrostatic immobilization of the photocatalyst in a unimolecular soft matter matrix, thereby prolonging (photo)catalytic activity due to slower photocatalyst degradation kinetics. We attribute this to a decreased propensity for hydrogenation of the pyrazine ring and, with that, slower degradation of the bridge and improved long\u2010term HER activity, as evidenced by a holistic spectroscopic characterization of the molecular and electronic structure of the photocatalyst. At the same time, the graft copolymer matrix does not hinder oxidative repair of the photocatalyst, thus enabling multiple repair cycles without noticeable loss of catalytic activity. We therefore regard this as a novel blueprint for a synergistic\n                    <jats:italic>molecule\u2010in\u2010matrix<\/jats:italic>\n                    combination for sustainable light\u2010driven catalysis.\n                  <\/jats:p>","DOI":"10.1002\/chem.71568","type":"journal-article","created":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T11:11:16Z","timestamp":1786705876000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Embedding a Dinuclear Ru\u2500Pt Photocatalyst Into Polyampholytic Graft Copolymer Matrix Enables Prolonged Hydrogen Evolution While Allowing Catalyst Repair"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-4839-3802","authenticated-orcid":false,"given":"Yurii","family":"Utievskyi","sequence":"first","affiliation":[{"name":"Institute of Organic Chemistry and Macromolecular Chemistry Friedrich Schiller University Jena  Jena Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6496-3429","authenticated-orcid":false,"given":"Alexander K.","family":"Mengele","sequence":"additional","affiliation":[{"name":"Institute of Inorganic Chemistry I Ulm University  Ulm Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariet","family":"Puthanagady","sequence":"additional","affiliation":[{"name":"Institute of Physical Chemistry Friedrich Schiller University Jena  Jena Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikita","family":"Vashistha","sequence":"additional","affiliation":[{"name":"Institute of Physical Chemistry Friedrich Schiller University Jena  Jena Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linda","family":"Zedler","sequence":"additional","affiliation":[{"name":"Institute of Physical Chemistry Friedrich Schiller University Jena  Jena Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3598-7656","authenticated-orcid":false,"given":"Christof","family":"Neumann","sequence":"additional","affiliation":[{"name":"Institute of Physical Chemistry Friedrich Schiller University Jena  Jena Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-4300-4742","authenticated-orcid":false,"given":"Marius","family":"M\u00fc\u00dfler","sequence":"additional","affiliation":[{"name":"Institute of Inorganic Chemistry I Ulm University  Ulm Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2388-1042","authenticated-orcid":false,"given":"Andrey","family":"Turchanin","sequence":"additional","affiliation":[{"name":"Institute of Physical Chemistry Friedrich Schiller University Jena  Jena Germany"},{"name":"Jena Center for Soft Matter (JCSM) Friedrich Schiller University Jena  Jena Germany"},{"name":"Center For Energy and Environmental Chemistry (CEEC) Friedrich Schiller University Jena  Jena Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benjamin","family":"Dietzek\u2010Ivan\u0161i\u0107","sequence":"additional","affiliation":[{"name":"Institute of Physical Chemistry Friedrich Schiller University Jena  Jena Germany"},{"name":"Leibniz Institute of Surface Engineering  Leipzig Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9635-6009","authenticated-orcid":false,"given":"Sven","family":"Rau","sequence":"additional","affiliation":[{"name":"Institute of Inorganic Chemistry I Ulm University  Ulm Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4685-6608","authenticated-orcid":false,"given":"Felix H.","family":"Schacher","sequence":"additional","affiliation":[{"name":"Institute of Organic Chemistry and Macromolecular Chemistry Friedrich Schiller University Jena  Jena Germany"},{"name":"Jena Center for Soft Matter (JCSM) Friedrich Schiller University Jena  Jena Germany"},{"name":"Center For Energy and Environmental Chemistry (CEEC) Friedrich Schiller University Jena  Jena Germany"},{"name":"Helmholtz Institute for Polymers in Energy Applications Jena (HIPOLE Jena)  Jena Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,14]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1039\/B802262N"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1021\/ar900225y"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccr.2007.08.021"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/0005\u20102728(93)90134\u20102"},{"key":"e_1_2_8_6_1","first-page":"449","article-title":"Chemical Storage of Light Energy.
