Exciting high symmetric 24-nuclear copper cluster with excellent selective adsorption capacity for cationic dyes.

The carbon-carbon double bond functionalized 24-nuclear copper cluster was successfully synthesized. The cluster can capture an impressive quantity of dyes, such as RhB (rhodamineB), MB (methylene blue) and CV (crystal violet). By the interaction between double bond and ions, the complex can selective separate cationic dyes from aqueous solution effectively. [ABSTRACT FROM AUTHOR]
