abstract
The convergent growth approach to dendritic macromolecules is a versatile method for the preparation of globular molecules with highly controlled three-dimensional architectures. The method, inspired from a classical organic disconnection approach, starts growth of the globular dendrimer at what will become its chain-ends and proceeds toward what will become its center. The convergent growth has been applied to the preparation of a number of unconventional dendritic block copolymers as well as hybrid globular-linear copolymers that are not readily accessed by other routes. Control of the chemistry and the precise location of the chain-ends in convergent dendrimers is essential for the preparation of micellar, amphiphilic, dipolar, or other structures that may be useful in applications as varied as drug delivery and molecular devices. 1994, Taylor & Francis Group, LLC.
