Abstract
Abstract Organic luminescent radicals have emerged as promising open‐shell emitters for advanced optoelectronic and sensing applications. Among them, the carbazole‐substituted tris(2,4,6‐trichlorophenyl)methyl radical (Cz‐TTM) exhibits remarkable photostability and emission efficiency compared with the parent TTM radical. Nevertheless, Cz‐TTM can be visibly degraded by indoor light irradiation and its photodegradation mechanism is poorly understood. Here, the study systematically investigates the photochemical behavior of Cz‐TTM in solutions, together with the influence of impurities on the photophysical properties of the compound. It is found that emissive and non‐emissive impurities are introduced depending…
