Thermally activated delayed fluorescence in neutral and cationic copper(I) complexes with the 2-(4-Thiazolyl)benzimidazole ligand 2023 Access copy available to the general public Unrestricted Cationic [Cu(P^P)(Htbz)]PF6 [P^P = xantphos, dpephos; Htbz = 2-(4-thiazolyl)benzimidazole] and the corresponding neutral complexes [Cu(P^P)(tbz)], obtained through deprotonation of the diimine ligand, have been synthesized with the aim of analyzing the role of the diphosphane and Htbz deprotonation in the emissive properties of these complexes. For the study of the diphosphane effect, the luminescence properties of these compounds have been compared with those of the reported analogous derivatives with Htbz and carborane diphosphanes. Complexes [Cu(P^P)(Htbz)]PF6 (P^P = xantphos, dpephos) and [Cu(dpephos)(tbz)] display thermally activated delayed fluorescence, which has been studied, revealing a ΔE(S1–T1) between 658 and 455 cm–1. Theoretical calculations indicate different origins for the absorptions, leading to the observed emissions. info:eu-repo/grantAgreement/ES/AEI/PID2019-104379RB-C21 info:eu-repo/grantAgreement/ES/DGA/E07-23R info:eu-repo/grantAgreement/ES/MINECO/BES2017-082997 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.3 2023 CHEMISTRY, INORGANIC & NUCLEAR 8 / 44 = 0.182 2023 Q1 T1 0.928 2023 Chemistry (miscellaneous) 2023 Q1 Physical and Theoretical Chemistry 2023 Q1 Inorganic Chemistry 2023 Q1 7.6 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Crespo, O.
