Abstract

A nested Cu24@Cu72 copper-organic framework, [Cu5(bdc)4(ina)2(H2O)3]·solvent (1, H2bdc = 1,3-benzenedicarboxylic acid and Hina = isonicotinic acid) based on paddlewheel Cu2(COO)4 SBUs, has been synthesized. There are three types of cages with different sizes and shapes: Cu24-cage, Cu60-cage and Cu72-cage. The Cu72-cage, which is the highest-nuclearity Cu-cage reported to date, encapsulates a Cu24-cage to form a double-walled Cu24@Cu72 cage-within-cage structure. Dye adsorption studies reveal that compound 1 can rapidly and selectively adsorb cationic dyes.
