【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）.更多还原
