Abstract A novel inorganic-organic hybrid polyoxoniobate framework based on crescent-like {SiNb18O54} building blocks and [Cu(en)]2+/K+ (en = ethylenediamine) linkers has been successfully made under hydrothermal condition. The compound is very stable under various conditions, and can selectively absorb crystal violet from aqueous solution. Additionally, the proton-conduction property of the compound was also studied.

一种超稳定的基于 {SiNb18O54} 的杂化聚氧铌酸盐骨架，用于从水溶液和质子传导中选择性去除结晶紫

摘要 基于新月形 {SiNb18O54} 结构单元和 [Cu(en)]2+/K+ (en = 乙二胺) 连接体，在水热条件下成功制备了一种新型无机-有机杂化聚氧铌酸盐骨架。该化合物在各种条件下都非常稳定，能选择性地从水溶液中吸收结晶紫。此外，还研究了该化合物的质子传导特性。
