Abstract A one-dimensional (1D) inorganic–organic hybrid based on sandwich-type copper(I)-iodide nanochain was synthesized for the first time. By replacing the copper(I) ions at the sandwich layer with silver(I) ions, a Cu(I)-Ag(I) bimetallic iodide nanochain was isolated. Although they are isostructural, the mixed-metallic one shows a larger band gap and stronger photoluminescence compared with the homometallic one, which may be contributed to the changed valence bands and metallophilic interactions modulated by the silver ions.

基于混合金属 Cu(I)-Ag(I) 碘化物的无机-有机杂化物：取代诱导的带隙扩大和发射增强

摘要 首次合成了一种基于夹心型碘化铜（I）纳米链的一维（1D）无机-有机杂化物。通过用银 (I) 离子替换夹层中的铜 (I) 离子，分离出 Cu(I)-Ag(I) 双金属碘化物纳米链。尽管它们是同构的，但与同质金属相比，混合金属显示出更大的带隙和更强的光致发光，这可能是由于银离子调节的价带变化和亲金属相互作用。
