Carborane-containing dendronized polymers were successfully synthesized using two different approaches up to the fourth generation. Nitroxide-mediated polymerization (NMP) was effective for the polymerization of carborane-functionalized styrenic monomers, leading to well-defined polymers with high boron content and narrow molecular weight distributions (PDI < 1.1). The resulting carborane-functionalized polymers could then be dendronized using a divergent approach to introduce aliphatic polyester dendrons of generation 1−4 grafted from the polymer backbone. This first approach afforded a maximum degree of dendronization of 70%. To increase the degree of dendronization, a first-generation macromonomer was polymerized using NMP to yield a fully functionalized first-generation dendronized polymer. This material was also dendronized up to the fourth generation. Both approaches produced water …
