Herein authors successfully developed a ring-fusion approach to extend the conjugation length of phenothiazines and synthesized a series of novel extended phenothiazines. The intriguing π-conjugation length-dependent photophys. and redox properties of these extended phenothiazines, and their photocatalytic performance towards visible-light-driven oxidative coupling reactions of amines were systematically investigated. As compared with the conventional phenothiazine (PTZ), all the extended phenothiazines displayed reversible redox behavior and maintained a strong excited-state reduction potential as well. Consequently, phenothiazines with longer effective conjugation lengths could efficiently catalyze the oxidative coupling of amines to imines under visible-light irradiation; by comparison, the shorter PTZ could only catalyze such reactions in the presence of UV light. Moreover, one PTZ showed superior catalytic performance which can result in better yields within a shorter reaction time, and in a broad substrate scope. Finally, a direct and efficient conversion of amines to imines under sunlight in an air atm. was successfully realized. Authors believe that their study including the new phenothiazine modification methodol. and the newly developed extended phenothiazine-based photocatalysts will open up a new way to develop novel phenothiazine-based materials for optoelectronic and catalytic applications. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Application of 93-04-9
