Surfactant 1‑Hexadecyl-3-methylimidazolium Chloride Can Convert One-Dimensional Viologen Bromoplumbate into Zero-Dimensional

A zero-dimensional N,N′-dibutyl-4,4′-dipyridinium
bromoplumbate, [BV]6[Pb9Br30], with
unusual discrete [Pb9Br30]12– anionic clusters was prepared via a facile surfactant-mediated solvothermal
process. This bromoplumbate exhibits a narrower optical band gap relative
to the congeneric one-dimensional viologen bromoplumbates.

通过简便的表面活性剂介导溶剂热法，成功制备得到一种零维N,N’-二丁基-4,4’-联吡啶鎓溴铅酸盐[BV]6[Pb9Br30]，其包含罕见的离散型[Pb9Br30]12–阴离子簇。相较于同系列的一维紫精溴铅酸盐，该溴铅酸盐的光学带隙更窄。
