    • 2O resonances were evaluated. In the fluorescence titrations at constant concentration of the molecular rod (c(rod) ≈ 0.01-0.02 mM, c(dendrophane) = 0.005-0.8 mM), the emission intensity of the rod decreased upon addition of dendrophane and the emission maxima of 4a/4b at saturation binding shifted by 5-16 nm to higher energy.
