CFN Research Activities

We are engaged in the synthesis and characterization of semiconducting molecules and macromolecules for photovoltaic applications, including functionalized polyalkylthiophenes and alternating electron-donating/electon-accepting-type structures, as well as block copolymers for surface patterning. We have expertise in a range of polymerization and polymer characterization techniques.
