This presentation will describe our recent work in developing new approaches for postpolymerization functionalization, specifically focusing on strategies that allow two distinct functional groups to be installed at one site along a polymer chain. We exploited the chemoselective nature of cyanuric chloride [2,4,6-trichlorotriazine (TCT)] to obtain ω,ω-heterodifunctionalized semitelechelic polymers, as well as multifunctional homopolymers (i.e., homopolymers that contain two distinct functional groups on each monomer unit). We will also describe our recent work that involved using telechelic polymers to probe the surface-localized hyperthermia of metal nanoparticles under microwave irradiation. This approach indicated the temperature near the surface of the nanoparticles was nearly 70 °C higher than the bulk solution temperature, but decreased rapidly with radial distance. This finding provides opportunities in the area of catalysis and processing and provides fundamental insight into the phenomenon of microwave heating.
