comprised of redox-active organic radicals have emerged as promising materials
for use in a variety of organic electronics, including fast-charging batteries.
Despite these advances, relatively little attention has been focused on the diversification
of the families of radicals that are commonly incorporated into polymer
frameworks, with most radical polymers being comprised of nitroxide radicals.
Here, we report two new examples prepared via ring-opening methathesis polymerization
containing 6-oxoverdazyl and nitronyl nitroxide radicals appended to their
backbones. The polymerization reaction and optoelectronic properties were
explored in detail, revealing high radical content and redox activity that may
be advantageous for their use as semiconducting thin films. Initial studies
revealed that current-voltage curves obtained from thin films of the title
polymers exhibited memory effects making them excellent candidates for use in
resistive memory applications.
