摘要：A novel Ru(bpy)3-viologen guest RPV and a reference compound PV are well designed and synthesized. Ru(bpy)3 based guest compound RPV prefers to form a novel U-type complex RPVSC4 with p-sulfonatocalix[4]arene (SC4) host. Binding manner of the complex has been fully studied by 1H NMR, ESI-MS and 2D NOE NMR spectra. The 1:1 Binding ratio is confirmed by UV-Vis measurement and the association constant is determined by 1H NMR titration. In this host-guest system, both Ru(bpy)3 and viologen group show strong interactions with the host SC4. Due to the unique U-type structure of RPVSC4, the competitive interactions between Ru(bpy)3 and viologen group were investigated as well. ? 2012 Elsevier Ltd. All rights reserved.
