irregular condensation of 1 by the removal of alkoxyl groups. B-1 exhibits high dye adsorption efficiency toward cationic dyes with a qe value of 651.3 mg/g at 298 K for methylene blue (MB). Moreover, B-1 can be used to selectively remove MB not only from mixed cationic–anionic dye solutions but also from some mixed cationic dyes, which is related to their structures.

钛-氧簇(TOCs)已被研究用于催化、能量存储和转移、发光等;然而,尚未报道使用 TOC 选择性吸附染料。在此,成功地制备了一种TOC化合物,其配制成[Ti 6 O 3 (O i Pr) 14 (TTFTC)] 4 ( 1,TTFTC =四硫富瓦烯-四羧酸盐),并对其进行了晶体学表征。化合物1具有由四个 Ti 6簇和四个棒状 TTFTC 连接器组装而成的环状结构。红色化合物1自缩合形成黑色聚合物有机-无机杂化材料(记为 B- 1),其特点是各种技术。B- 1是一种无定形的 TiO 材料,由1通过去除烷氧基不规则缩合而成。B- 1对阳离子染料表现出较高的染料吸附效率,在 298 K 时对亚甲基蓝 (MB)的q e值为 651.3 mg/g。此外,B- 1不仅可以从混合的阳离子-阴离子染料溶液中选择性地去除MB,还可以从一些混合的阳离子染料中选择性地去除MB,这与它们的结构有关。动力学、等温线和热力学研究表明,准二级动力学模型和
