Several 2,5-diaryl-1,1-dimethyl-3,4-diphenylsiloles (with aryl = p-cyanophenyl (1), m,p-bis(methylthio)phenyl (2), p-N,N-dimethylaminophenyl (3), 2,2′-bipyridin-6-yl (4)) were synthesized and characterized by UV-vis, fluorescence, and NMR spectroscopy, along with crystal structure determinations for 1 and 2. Compounds 1-4 in methylene chloride were combined with 1-10 equiv of M(ClO4)2 (M = Ni, Cu, Hg) in methanol, and the resulting solutions were monitored by UV-vis and fluorescence spectroscopy. Compound 1 showed slight effects for each metal, 2 exhibited fluorescence quenching selectively for Hg(II), 3 showed significant changes for all cations, and 4 generally demonstrated fluorescence quenching for all cations. A discussion of the causes behind these changes is also presented.
