In this article, dendronized polymers with rigid backbones were synthesized from enediyne-containing Frechet-type dendrimers. Two generations of dendrimers were conically incorporated with 3-(2-(2-(trimethylsilyl)ethynyl)phenyl)prop-2- yn-1-ol. The trimethylsilyl protection groups of enediyne units were subsequently removed, and two types of brush polymers with rigid conjugated backbone were prepared through Bergman cyclization polymerization at elevated temperature under vacuum. The dendronized polymers were characterized with GPC, IR, UV-vis, and NMR spectroscopy. Furthermore, the morphology of the dendronized polymer was revealed by atomic force microscopy.

Hanging on: Pristine graphene was grafted with conjugated polymers through addition and propagation of diradicals generated from Bergman cyclization of enediyne-containing dendrimers. The surface functionalization was confirmed with TGA, FTIR and Raman spectroscopy, and AFM analysis. The sp2 network of graphene is only slightly destroyed, as revealed by conductivity measurements.
