文摘

A series of luminescent dinuclear gold(I) alkynylcalix[4]crown-5 complexes, [(R_nR'_3-nP)Au]₂L(n = 0-3) (R = Ph, R' = o-Tol, p-Tol) (H₂L = 5,17-diethynyl-25,27-dimethoxycalix[4]arene-crown-5, have been synthesized and structurally characterized. The binding properties ofthe complexes toward alkali metal ions (K⁺ and Na⁺) have been studied by UV-visiblespectrophotometry. The dinuclear gold(I) alkynylcalix[4]crown-5 complexes were shown toexhibit preferential binding toward K⁺ over Na⁺ ions.
