title: Calix[3]carbazole: A C3-symmetrical receptor for barium ion.
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.
