Symmetry Breaking Charge Transfer Mechanism in Sulfone-Functionalized Diradical Near-Infrared Emitters
Zixi Liu, Zhuoran Kuang, Andong Xia
Beijing University of Posts and Telecommunications, China
Diradicaloids, characterized by two weakly coupled interacting single electrons, exhibit unique physicochemical properties and hold significant potential for applications in bipolar field-effect transistors (OFETs), organic spintronics, and near-infrared (NIR) dyes.Previously reported sulfone-functionalized diradicaloids demonstrate a large Stokes shift and achieve the longest emission wavelengths among known organic fluorescence radicals. However, many diradical emitters suffer from low photoluminescence quantum yields. Thus, understanding the excited-state relaxation mechanisms of sulfone-functionalized diradicaloids is crucial for designing NIR open-shell molecular materials. In this study, we characterized sulfone-functionalized ChiChibabin's hydrocarbon derivatives, SD-1 and SD-2 with different substituents (H/CF3) on the molecular skeleton. Experimental and theoretical calculations reveal that SD-1 and SD-2 contain high diradical character and small ΔES−T, indicating that both are open-shell singlet diradical molecule. The steady-state fluorescence spectroscopy reveals that two diradicaloids exhibit emission properties sensitive to solvent polarity.This observation suggests the presence of significant intramolecular charge transfer characteristics, which may arise from symmetry breaking within their electronic structures. Femtosecond time-resolved transient absorption spectroscopy reveals the formation of symmetry-breaking charge transfer (SBCT) state in polar solution, and the corresponding kinetics are correlated to the solvent reorientation dynamics and dihedral torsional motion. Quantitative calculations indicate that the charge transfer feature in these diradicaloids may come from the overlap with the single electron SOMO orbitals and is significantly regulated by substituents (H/CF3) on the molecular skeleton. The quenching of SBCT emission in the NIR region primarily results from the fast charge recombination, which is anticipated to enhance its potential as an efficient NIR emitter by suppressing charge recombination processes. Overall, this study demonstrates that the sulfone-functionalized diradical compounds SD-1 and SD-2 possess unique SBCT properties, making them promising candidates for efficient near-infrared emitters. Their ability to inhibit charge recombination addresses the challenge of low photoluminescent quantum yields, paving the way for advancements in organic optoelectronic applications.
