Convergent synthesis, phenylacetylene dendrimers

Effect of Varying Focal Point Functionality on the Convergent Synthesis of Phenylacetylene Dendrimers... 

However, Moore and his co-workers [56] showed that by increasing the size of the building block as a function of generation, it is possible to reduce if not eliminate the problem of steric hindrance. He developed the concept of dendritic wedges including linear extensions and applied it to the convergent synthesis of phenylacetylene dendrimers.
