Abstract: In accordance with the present invention, there is provided a method of preparing higher generation 1?3 C-branched polyamide dendrons. The combination of commercially available acryloyl chloride with 1?3 C-branched amines, e.g., di-tert-butyl 4-[2-(tert-butoxycarbonyl)ethyl]-4-aminoheptanedioate, resulted in generally high yields of acryl amides, which upon treatment with other reagents, generated the desired higher generation dendrons. These second and third generation dendrons were fully characterized and compared to the samples prepared from a convergent synthesis.

Abstract: Unimolecular micelies, generally referred to as cascade polymers, are constructed via the addition of successive layers, or tiers, of designed monomers, or building blocks, that possess a predetermined, branched superstructure consisting of connected physical matter inherently defining an internal void volume or void area within the molecular framework. Each of the branches define a flexible arm from a central core atom and terminate with a hydrodynamic reactive group. A method is described for manipulating such cascade polymers.

Abstract: Unimolecular micelles, generally referred to as cascade polymers, are constructed via the addition of successive layers, or tiers, of designed monomers, or building blocks, that possess a predetermined, branched superstructure consisting of connected physical matter inherently defining an internal void volume or void area within the molecular framework. Reactive sites located on the framework and hence within the void regions are capable of being chemically transformed to allow covalent and noncovalent incorporation of one or more guest species into the said void regions. Further, a method is described for making such cascade polymers that includes the steps of forming a unimolecular micelle containing internal void areas with accessible reactive sites capable of bonding to at least one guest after construction of the said unimolecular micelle. The guests are contained within the internal void volume of the cascade polymer and are available and accessible for additional chemical modification.
