    • The spectra of 4-6 in Figure 4 are quite sharp although they represent diastereomers of the complexes which differ by the clockwise/ counterclockwise array of the ureas on their ends. Apparently this level of information is not communicated between the ends of the assemblies.

    • note
    • Differences in both shape and functional groups from the standards make the rentention times of assemblies 2 and 4-6 necessarily deviate from the standard calibration line. These assemblies are, however, similar to each other in these regards, making molecular weight estimations reasonable, although only in a comparative sense (see ref 8).

    • note
    • The exclusion limit of the column used is ≈30 kDa (based on polystyrene standards), which corresponds to a retention time on the order of 6.3 min. Beyond this point there no longer exists a linear correlation between molecular weight and retention time. All of the polymeric systems investigated have retention times below this limit, thereby precluding molecular weight assignments. Additionally, polycap traces tended to be prohibitively broad, preventing even direct comparison to polystyrene standards.
