【摘要】 硒/碲醚易与Cu(Ⅰ)构筑获得稳定结构物质,我们设计合成基于硒/碲醚配体的系列卤化亚铜簇合物[Cu2X2L2]n,并研究其构效性能。通过原位构筑得到的核-壳型铜簇的纳米复合物TiO2@[Cu2I2L2]n,具有优异的可见光催化活性。[1]
【Abstract】 Soft Se/Te donor atoms can form stable copper(Ⅰ) complexes than N, P and O. Our continued interest in the coordination chemistry of selenoethers/telluroethers led us to investigate the synthesis and characterization of new neutral chalcogenoether copper(Ⅰ) cluster [Cu2X2L2]n and explore their photocatalytic activity. A new in situ surface assembly strategy was designed for the preparation of low-cost polymeric copper(Ⅰ) cluster sensitized TiO2, core-shell TiO2@[Cu2I2L2]n nanocomposites, based upon selenoanthracene and CuI [1]. It shows efficient photocatalytic activity to aqueous Cr(Ⅵ) reduction under visible-light(λ > 400 nm), with good chemical stability and long term activity(Fig.1).
