《Novel phenoxazine-benzonitrile and phenothiazine-benzonitrile donor-acceptor molecules with thermally activated delayed fluorescence (TADF)》 was written by Baraket, Faiza; Pedras, Bruno; Torres, Erica; Brites, Maria Joao; Dammak, Mohamed; Berberan-Santos, Mario N.. COA of Formula: C7H4BrN And the article was included in Dyes and Pigments in 2020. The article conveys some information:
Four novel TADF emitters, containing phenothiazine and phenoxazine as electron-donors and benzonitrile derivatives as electron-acceptors were synthesized and fully characterized. Their photophys. (absorption and emission spectra, molar extinction coefficients, fluorescence quantum yields and lifetimes) and electrochem. properties (HOMO and LUMO energy levels) were measured, and drop-cast solid films of the four compounds were obtained to perform TADF studies. The obtained values for ΔEST indicate that these compounds are candidates for OLED applications. The experimental part of the paper was very detailed, including the reaction process of 4-Bromobenzonitrile(cas: 623-00-7COA of Formula: C7H4BrN)
4-Bromobenzonitrile(cas: 623-00-7) has been used in the synthesis of 4-iodobenzonitrile via photo-induced aromatic Finkelstein iodination reaction.COA of Formula: C7H4BrN It can also be used as an aryl halide test compound in developing greener reaction conditions for Suzuki cross-coupling between aryl halides and phenyl boronic acid.
