In this article, an anthraquinone-based copper(I)cyclic trinuclear complex(1) was designed and it featured strong visible light absorption, high charge separation efficiency and photochemical properties. Complex 1 as a heterogeneous photocatalyst can efficiently catalyze homo-coupling of terminal alkynes and denitrification-oxidative coupling reaction between hydrazinopyridine and terminal alkynes with excellent yield(up to 99%), broad substrate tolerance(27 examples) and superior reusability(up to 10 cycles without loss of performance) under mild conditions.展开更多
