Porphyrins, renowned for their exceptional photophysical properties, photostability, and prevalence in natural catalytic processes, are attracting significant attention as promising photocatalysts for reactions proceeding through energy transfer and one-electron transfer. In this work, we synthesized the indium(III) complex of 2-[4-(diethoxyphosphoryl)phenyl]-1H-imidazo[4,5-b]-5,10,15,20-tetramesitylporphyrin (InTMPIP) and explored its application as a photocatalyst for the oxidation of sulfides by dioxygen or air. Complex InTMPIP was found to generate singlet oxygen with quantum yield of 0.92 (toluene) and enables efficient photooxidation of sulfides to sulfoxides by dioxygen in \u201cgreen\u201d acetonitrile\/water (4:1 v\/v) or methanol\/chloroform (2:1 v\/v) solvent mixtures with almost quantitative yield. Furthermore, InTMPIP was grafted onto hydrated mesoporous titania and materials InTMPIP\/TiO2-1 and InTMPIP\/TiO2-2 with different In\/Ti ratios were obtained and investigated. The composition and structure of the materials were studied using a combination of elemental analysis, various spectroscopic methods, gas adsorption measurements, and SEM imaging. Finally, the photocatalytic efficiency of InTMPIP\/TiO2-2 was explored in aerobic photooxidation of sulfides. The heterogenized complex enables selective synthesis of sulfoxides under \u201cgreen\u201d conditions; however, it is prone to leaching into the solution when irradiated with both blue and red LEDs.<\/jats:p>","DOI":"10.3390\/molecules30040864","type":"journal-article","created":{"date-parts":[[2025,2,13]],"date-time":"2025-02-13T09:05:42Z","timestamp":1739437542000},"page":"864","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Indium Imidazo[4,5,-b]porphyrins as Photocatalysts for Oxidation of Sulfides"],"prefix":"10.3390","volume":"30","author":[{"given":"Inna A.","family":"Abdulaeva","sequence":"first","affiliation":[{"name":"Institut de Chimie Mol\u00e9culaire de l\u2019Universit\u00e9 de Bourgogne, UMR 6302 CNRS, Universit\u00e9 de Bourgogne, 9 Avenue Alain Savary, BP 47870, 21078 Dijon, CEDEX, France"},{"name":"Frumkin Institute of Physical Chemistry and Electrochemistry, Russian Academy of Sciences, Leninsky Pr. 31-4, 119071 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1640-841X","authenticated-orcid":false,"given":"Mikhail A.","family":"Filatov","sequence":"additional","affiliation":[{"name":"School of Chemical and Biopharmaceutical Sciences, Technological University Dublin, City Campus, Grangegorman, Dublin 7, D07 ADY7 Dublin, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Azhar","family":"Kechiche","sequence":"additional","affiliation":[{"name":"ENS de Lyon, CNRS, LCH, UMR 5182, 69342 Lyon, CEDEX 07, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6707-6868","authenticated-orcid":false,"given":"Alla","family":"Bessmertnykh-Lemeune","sequence":"additional","affiliation":[{"name":"Institut de Chimie Mol\u00e9culaire de l\u2019Universit\u00e9 de Bourgogne, UMR 6302 CNRS, Universit\u00e9 de Bourgogne, 9 Avenue Alain Savary, BP 47870, 21078 Dijon, CEDEX, France"},{"name":"ENS de Lyon, CNRS, LCH, UMR 5182, 69342 Lyon, CEDEX 07, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Chao, H., Li, R.-H., Ye, B.-H., Li, H., Feng, X.-L., Cai, J.-W., Zhou, J.-Y., and Ji, L.-N.
