Abstract

A number of dendrimers based on polyhedral silsesquioxane cores have been synthesised and characterised. The new molecules are prepared by repetitive hydrosilation/alkenylation reactions, which provide a facile and high yield route to dendrimers with a high density of branch ends per generation. Judicious choice of hydrosilating agent [HSiCl3, H (CH3) SiCl2 or H (CH3) 2SiCl] produces dendrimers with varying numbers of chain ends, and ...
