Copper-doped semiconductors are designed to photoassist the alkyne-azide cycloaddition catalysis by Cu(I). Upon irradiation, injection of electrons from the semiconductor into copper oxide nanostructures produces the catalytic Cu(I) species. The new catalysts are air- and moisture-tolerant and can be readily recovered after use and reused several times.
铜掺杂半导体的设计目的是通过 Cu(I) 光辅助炔烃-叠氮化物环加成催化。在光照下,半导体中的电子注入氧化铜纳米结构中,产生催化 Cu(I) 物种。这些新型催化剂具有耐空气和耐湿性,使用后可以很容易地回收并重复使用几次。
