摘要：
We described two molecular systems containing tricyanovinyl dyes as signalling Subunits and crown ether macrocycles Lis binding sites, which act as triple-channel sensing receptors. Signalling was observed through UV-vis, fluorescence and electrochemical measurements. With these three techniques sensing of certain metal cations was achieved via multiple signalling patterns.
