Herein, zinc porphyrin derivatives bearing a <jats:italic>meta<\/jats:italic>\u2010pyridyl group at the <jats:italic>meso<\/jats:italic> position were prepared and their assemblies studied in chloroform. Among the porphyrins studied, one with a carbamoylpyridyl moiety gave a distinct <jats:sup>1<\/jats:sup>H\u2005NMR spectrum in CDCl<jats:sub>3<\/jats:sub>, which allowed the supramolecular structure in solution to be probed in detail. Ring\u2010current\u2010induced chemical\u2010shift changes in the <jats:sup>1<\/jats:sup>H\u2005NMR spectrum, together with vapor\u2010pressure osmometry and diffusion\u2010ordered NMR spectroscopy, among other evidence, suggested that the porphyrin molecules form a trimer with a triangular cone structure. Incorporation of a directly linked porphyrin\u2013ferrocene dyad with the same assembling properties in the assemblies led to a rare example of a light\u2010harvesting\/charge\u2010separation system in which an energy gradient is incorporated and reductive quenching occurs.<\/jats:p>","DOI":"10.1002\/chem.202003327","type":"journal-article","created":{"date-parts":[[2020,10,30]],"date-time":"2020-10-30T01:33:50Z","timestamp":1604021630000},"page":"4053-4063","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["A Light\u2010Harvesting\/Charge\u2010Separation Model with Energy Gradient Made of Assemblies of <i>meta<\/i>\u2010Pyridyl Zinc Porphyrins"],"prefix":"10.1002","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9974-6037","authenticated-orcid":false,"given":"Joe","family":"Otsuki","sequence":"first","affiliation":[{"name":"Department of Materials and Applied Chemistry College of Science and Technology Nihon University  1-8-14 Kanda Surugadai, Chiyoda-ku Tokyo 101-8308 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takumi","family":"Okumura","sequence":"additional","affiliation":[{"name":"Department of Materials and Applied Chemistry College of Science and Technology Nihon University  1-8-14 Kanda Surugadai, Chiyoda-ku Tokyo 101-8308 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3434-4632","authenticated-orcid":false,"given":"Kosuke","family":"Sugawa","sequence":"additional","affiliation":[{"name":"Department of Materials and Applied Chemistry College of Science and Technology Nihon University  1-8-14 Kanda Surugadai, Chiyoda-ku Tokyo 101-8308 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7969-2972","authenticated-orcid":false,"given":"Shin\u2010ichiro","family":"Kawano","sequence":"additional","affiliation":[{"name":"Department of Chemistry Graduate School of Science Nagoya University  Furocho Chikusa-ku Nagoya 464-8602 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6395-4536","authenticated-orcid":false,"given":"Kentaro","family":"Tanaka","sequence":"additional","affiliation":[{"name":"Department of Chemistry Graduate School of Science Nagoya University  Furocho Chikusa-ku Nagoya 464-8602 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4377-7541","authenticated-orcid":false,"given":"Takehiro","family":"Hirao","sequence":"additional","affiliation":[{"name":"Department of Chemistry Graduate School of Advanced, Science and Engineering Hiroshima University  1-3-1 Kagamiyama Higashi-Hiroshima 739-8526 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0945-2893","authenticated-orcid":false,"given":"Takeharu","family":"Haino","sequence":"additional","affiliation":[{"name":"Department of Chemistry Graduate School of Advanced, Science and Engineering Hiroshima University  1-3-1 Kagamiyama Higashi-Hiroshima 739-8526 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu Jin","family":"Lee","sequence":"additional","affiliation":[{"name":"Spectroscopy Laboratory for Functional \u03c0-Electronic Systems, and Department of Chemistry Yonsei University  Seoul 03722 South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seongsoo","family":"Kang","sequence":"additional","affiliation":[{"name":"Spectroscopy Laboratory for Functional \u03c0-Electronic Systems, and Department of Chemistry Yonsei University  Seoul 03722 South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongho","family":"Kim","sequence":"additional","affiliation":[{"name":"Spectroscopy Laboratory for Functional \u03c0-Electronic Systems, and Department of Chemistry Yonsei University  Seoul 03722 South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,12,23]]},"reference":[{"key":"e_1_2_7_1_1","volume-title":"Handbook of Porphyrin Science Vol.\u20051","author":"Kadish K.
