Guiding the Self‐Assembly of a Second‐Generation Polyphenylene Dendrimer into Well‐Defined Patterns

Abstract A second‐generation polyphenylene dendrimer 1 is shown to self‐assemble into nanofibers. To guide the formation of the dendrimer fibers into well‐defined patterns, 1H,1H,2H,2H‐perfluorodecyltrichlorosilane is grafted in the gas phase onto a silicon substrate. De‐wetting of the solution on the nanopatterned surface results in the formation of a nanostructured template, into which fiber growth subsequently occurs under the constraints set by the de‐wetted morphology.
