The maximum band UV-Vis absorption wavelengths of the tris(\u03b2-diketonato)iron(III) complexes were in the range of 270\u2013380 nm. The complexes have very good solubility in various solvents such as chloroform, dichloromethane, ethyl acetate, tetrahydrofurane, dimethylsulphoxide and dimethylformamide. After the syntheses and characterization processes, spectroscopic and electrochemical properties of these tris(\u03b2-diketonato)iron(III) complexes were investigated. A density functional theory (DFT) study related to the spectroscopic and electrochemical properties of the tris(\u03b2-diketonato)iron(III) complexes was used to investigate the possible application of these complexes as dye sensitizers or redox mediators in dye-sensitized solar cells.<\/jats:p>","DOI":"10.3390\/molecules27123743","type":"journal-article","created":{"date-parts":[[2022,6,12]],"date-time":"2022-06-12T22:37:20Z","timestamp":1655073440000},"page":"3743","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["UV-Vis Spectroscopy, Electrochemical and DFT Study of Tris(\u03b2-diketonato)iron(III) Complexes with Application in DSSC: Role of Aromatic Thienyl Groups"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8104-7684","authenticated-orcid":false,"given":"Marrigje M.","family":"Conradie","sequence":"first","affiliation":[{"name":"Department of Chemistry, University of the Free State, P.O.
