The synthesis of a series of amine‐cored N , N ‐dimethyl‐terminated polyamidoamine dendrons with the potential to be modified at their focal point is reported. The use of an aniline core enables the target molecules to be synthesised without resorting to the use of a time‐consuming and expensive protection/deprotection strategy. After synthesising these molecules significant frothing in aqueous solution at millimolar concentrations was noticed, a property associated with aggregation. The critical micelle concentrations were therefore measured and found to occur at relatively low dilutions (in the range 10 −4 –10 −5 mol L −1 ). Copyright © 2006 Society of Chemical Industry
