This combination of properties has been achieved by functionalizing the periphery of hypervalent and highly electron-deficient phosphorus(V) and antimony(V) centered porphyrins with electron-rich triphenylamine (TPA) groups. As a result of the large difference in electronegativity between the porphyrin ring and the peripheral groups, their absorption profiles show several strong charge transfer transitions, which in addition to the porphyrin-centered \u03c0 \u2192 \u03c0* transitions, make them panchromatic black dyes with high absorption coefficients between 200 and 800 nm. Time-resolved optical and electron paramagnetic resonance (EPR) studies show that the lowest triplet state also has ICT character and is populated by spin\u2013orbit coupled intersystem crossing.<\/jats:p>","DOI":"10.1021\/jacs.4c06674","type":"journal-article","created":{"date-parts":[[2024,9,9]],"date-time":"2024-09-09T08:37:19Z","timestamp":1725871039000},"page":"25403-25408","source":"Crossref","is-referenced-by-count":20,"title":["Intramolecular\nCharge Transfer and Spin\u2013Orbit\nCoupled Intersystem Crossing in Hypervalent Phosphorus(V) and Antimony(V)\nPorphyrin Black Dyes"],"prefix":"10.1021","volume":"146","author":[{"given":"Jam Riyan","family":"Hamza","sequence":"first","affiliation":[{"name":"University of Minnesota Duluth , , , ,","place":["Duluth, Minnesota, United States, 55812"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5934-5666","authenticated-orcid":true,"given":"Jatan K.","family":"Sharma","sequence":"additional","affiliation":[{"name":"University of North Texas , , , ,","place":["Denton, Texas, United States, 76203-5017"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul A.","family":"Karr","sequence":"additional","affiliation":[{"name":"Wayne State College , , 1111 Main Street , , ,","place":["Wayne, Nebraska, United States, 68787"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6214-9260","authenticated-orcid":true,"given":"Art","family":"van der Est","sequence":"additional","affiliation":[{"name":"Brock University , , , ,","place":["St. Catharines, Ontario, Canada, L2S 3A1"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3815-8949","authenticated-orcid":true,"given":"Francis","family":"D\u2019Souza","sequence":"additional","affiliation":[{"name":"University of North Texas , , , ,","place":["Denton, Texas, United States, 76203-5017"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6007-8801","authenticated-orcid":true,"given":"Prashanth K.","family":"Poddutoori","sequence":"additional","affiliation":[{"name":"University of Minnesota Duluth , , , ,","place":["Duluth, Minnesota, United States, 55812"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2024,9,9]]},"reference":[{"key":"2026101614062712000_cit1","doi-asserted-by":"publisher","first-page":"12330","DOI":"10.1021\/cr5001964","article-title":"Meso-Substituted Porphyrins\nfor Dye-Sensitized Solar Cells","volume":"114","author":"Urbani","year":"2014","journal-title":"Chem.
