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 on a silicon substrate. Dewetting of the solution on the nano-patterned surface results in the formation of a nano-structured template, into which fiber growth subsequently occurs under the constraints set by the dewetted morphology.
