A series of luminescent dinuclear gold(I) alkynylcalix[4]crown-5 complexes, [(RnR′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 of the complexes toward alkali metal ions (K+ and Na+) have been studied by UV - visible spectrophotometry. The dinuclear gold(I) alkynylcalix[4]crown-5 complexes were shown to exhibit preferential binding toward K+ over Na+ ions.
