Abstract
The binding ability of calix[3]carbazole (1) to metal ions has been investigated. It is found that 1 could serve as a non crown ether based, C3-symmetrical receptor for Ba2+ via the marriage of cation–π and cation–dipole interactions. FID assay further illustrates that 1 could selectively interact with Ba2+ over Pd2+. A possible binding mechanism for [1-Ba2+] complex is proposed.
