Abstract
The synthesis of a series of cascade molecules (dendrimers) in which the core and branch points are phosphonium ion sites has been accomplished. The primary cores of these cascade molecules are either tridirectional or tetradirectional for the development of the generations of the cascade structure. Secondary branch points, also phosphonium ion sites, are all tridirectional for the development of further generations of the cascade structure.
