This study focuses on synthesizing tin porphyrins with germyl- and silyl-alkenyl substituents, addressing gaps in structural characterization and solubility behavior. Additionally, their potential in bulk-heterojunction solar cells is investigated. The synthetic pathways for these porphyrins are established, and their structural properties are analyzed using single crystal X-ray diffraction. The solubility of the synthesized porphyrin (<b>5</b>) is compared with <i>meso</i>-tetraaryl and <i>meso</i>-tetraalkyl free-base porphyrins. Electrochemical properties are studied through cyclic voltammetry, and density functional theory (DFT) calculations provide insights into the highest occupied and lowest unoccupied molecular orbitals. Despite promising optical and electrochemical properties, the solar cell performance of the synthesized porphyrins remains moderate, highlighting the need for further functionalization to enhance the power conversion efficiency.</p>","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 24","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/ejic.202500188","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144915147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
