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 Ba(2+) via the marriage of cation-π and cation-dipole interactions. FID assay further illustrates that 1 could selectively interact with Ba(2+) over Pd(2+). A possible binding mechanism for [1-Ba(2+)] complex is proposed. |
