This structural motif was expected to promote strong electronic coupling between the electron donors and the electron acceptor, a hypothesis that was confirmed in a full\u2010fledged physicochemical investigation focusing on the ground and excited state reactivities. As far as the ground state is concerned, absorption and electrochemical assays indeed reveal a notable redistribution of electron density, that is, from the electron\u2010donating [Ru(CO)Pc] to the electron\u2010accepting PDIpy<jats:sub>4<\/jats:sub>. The most important thing to note in this context is that both the [Ru(CO)Pc] oxidation and the PDIpy<jats:sub>4<\/jats:sub> reduction are rendered more difficult in <jats:bold>1<\/jats:bold> than in the individual building blocks. Likewise, in the excited state, strong electronic communication is the inception for a rapid charge\u2010transfer process in photoexcited <jats:bold>1<\/jats:bold>. Regardless of exciting [Ru(CO)Pc] or PDIpy<jats:sub>4<\/jats:sub>, spectral characteristics of the [RuPc] radical cation (broad absorptive features from 425 to 600\u2005nm with a maximum at 575\u2005nm, as well as a band centered at 725\u2005nm) and of the PDI radical anion (780\u2005nm maximum) emerge. The correspondingly formed radical ion pair state lasts for up to several hundred picoseconds in toluene, for example. On the other hand, employing more polar solvents, such as dichloromethane, destabilizes the radical ion pair state.<\/jats:p>","DOI":"10.1002\/chem.201002963","type":"journal-article","created":{"date-parts":[[2011,3,22]],"date-time":"2011-03-22T08:09:10Z","timestamp":1300781350000},"page":"5024-5032","source":"Crossref","is-referenced-by-count":45,"title":["Synthesis, Characterization, and Photoinduced Energy and Electron Transfer in a Supramolecular Tetrakis (Ruthenium(II) Phthalocyanine) Perylenediimide Pentad"],"prefix":"10.1002","volume":"17","author":[{"given":"Angel J.","family":"Jim\u00e9nez","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bruno","family":"Grimm","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victoria L.","family":"Gunderson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael T.","family":"Vagnini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandra","family":"Krick\u2005Calderon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.
