Photochromic mols. have received a lot of interest in potential applications. The development of the phenoxyl-imidazolyl radical complex (PIC), which generates two nonequivalent radicals upon light irradiation along with the fast photochem. reaction, is crucial for photoresponsive materials. However, as a novel photochromic compound, the low photosensitivity of PIC derivatives has limited their practical applications. Herein, increased photosensitivity and absorption coefficients of PIC derivatives were achieved while keeping the thermal back reaction rate by introducing the substitution of aryl groups. This strategy gives significant insight into the development of desirable fast photochromic compounds based on the PIC framework. The experimental part of the paper was very detailed, including the reaction process of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6COA of Formula: C12H17BO2)
4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6) also known as boronate ester, is generally used in metal-catalyzed C-C bond formation reactions like Suzuki–Miyaura reaction.COA of Formula: C12H17BO2
