    • The incipient formation of a 2:1 complex is easily deduced by the deviations, in the absorbance versus αCD concentration plots, from the trend expected under the hypothesis of the existence of a 1:1 complex only.

    • A similar effect could also be caused by partial protonation in the presence of an acidic buffer. This fact should be taken into account, when discussing the behaviour of aminoacid guests 16-19.

    • note
    • It is strange to observe that in some occasions (see Ref. 20b) this thesis has been supported with experimental data for which there is the concrete danger of dealing with a pseudo-compensation effect. In fact, it should be considered that, under these circumstances, a real compensation would be indistinguishable from a false one.
