In order to improve the photocatalytic efficiency, a kind of thermal delayed fluorescence (TADF) photocatalyst of tricarbazolyl phthalonitrile was designed and synthesized. A system for the dehalogenation of aryl halohydrocarbons was established, using TADF material as photocatalyst and disulfide as hydrogen transfer catalyst. Different organic halides (including C—Br bonds and C—Cl bonds) can be dehalogenated with moderate to excellent yields. Compared with 2,4,5,6-tetrakis- (carbazol-9-yl)-1,3-dicyanobenzene (4CzIPN), the representative thermal delayed fluorescent material, 4-(N,N-dimethylami- no)-3,5,6-tri(9-carbazolyl)phthalonitrile (3CzDMAPN) has higher catalytic efficiency and specificity.

Key words: photocatalysis, dehalogenation
