Pushing the Synthetic Limit: Polyphenylene Dendrimers with “Exploded” Branching Units—22‐nm‐Diameter, Monodisperse, Stiff Macromolecules

Abstract

Structural perfection up to the fifth generation of a polyphenylene dendrimer has been achieved by inserting p-terphenyl spacers into the arms of each branching unit (see picture). The stiff, monodisperse macromolecules with diameters up to 22 nm were synthesized in a stepwise manner, during which the topology of the branching units was controlled. Dendrimers containing up to 1368 phenyl rings with high porosity were generated.
