Isomeric benzodifuran (BDF), benzodithiophene (BDT) and benzodiselenophene (BDS) analogs of phenanthrene, in which the two heteroaromatic rings are ortho-fused onto a benzene ring, represent convenient frameworks as functional materials in organic electronics. The orientation of the two condensed heteroaromatic rings with respect to the central benzene ring provides diverse structural isomers, which significantly differ in degrees of curvature, electronic and electrochemical properties. Furthermore, tailored modification and functionalization strategies enable fine-tuning of their intrinsic properties, leading to unique systems. This review offers a comprehensive overview of synthetic methodologies for constructing isomeric BDF, BDT and BDS skeletons, alongside an analysis of their electrochemical properties as influenced by the nature of heteroatoms. Finally, the most relevant applications of these systems, ranging from optoelectronics, supramolecular chemistry, and emerging biological studies, are discussed, providing valuable insights for future research direction.<\/jats:p>","DOI":"10.3390\/molecules31030425","type":"journal-article","created":{"date-parts":[[2026,1,26]],"date-time":"2026-01-26T15:48:30Z","timestamp":1769442510000},"page":"425","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Phenanthrene-like Benzodichalcogenophenes: Synthesis, Electrochemical Behavior and Applications"],"prefix":"10.3390","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4137-0089","authenticated-orcid":false,"given":"Valentina","family":"Pelliccioli","sequence":"first","affiliation":[{"name":"Department of Chemistry, Universit\u00e0 degli Studi di Milano, Via Golgi 19, I-20133 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1981-4659","authenticated-orcid":false,"given":"Serena","family":"Arnaboldi","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Universit\u00e0 degli Studi di Milano, Via Golgi 19, I-20133 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9540-9073","authenticated-orcid":false,"given":"Silvia","family":"Cauteruccio","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Universit\u00e0 degli Studi di Milano, Via Golgi 19, I-20133 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"6442","DOI":"10.1039\/D2CS00139J","article-title":"Group 16 conjugated polymers based on furan, thiophene, selenophene, and tellurophene","volume":"51","author":"Ye","year":"2022","journal-title":"Chem.
