Self-assembling dendrimers
-
of special interest. The first example of large dendritic wedges self-assembled by hydrogen-bonding interactions. Evidence for discrete hexameric structure is primarily obtained from molecular weight determination of the complexes by standard polymer techniques. Convincing data is provided for several of the smaller complexes but we would argue that the data presented for the highest generation wedge does not necessarily imply aggregation into a discrete hexagonal array, and other interpretations are possible.

Intramolecular cyclisation in hyperbranched polyesters

13C NMR spectroscopy shows intramolecular cyclisation to be insignificant, that is, less than 5%. This conclusion is supported by comparison of Mn values determined spectroscopically by end-group counting and that determined by osmometry.
