Abstract: Disclosed herein are embodiments of a bi-functionalized dicyclopentadiene monomer and polymer embodiments formed therefrom. The monomer embodiments exhibit tunability and can be used to form thermally stable homopolymers, copolymers, and/or crosslinked polymers.

Abstract: A family of novel diazirine-based molecules is disclosed, as well as methods of manufacture and uses thereof. These compounds allow non-functionalized polymers, such as polyolefins, to crosslink via C—H insertion. Such a C—H insertion process is useful, for example, for the covalent adhesive bonding of low surface energy films or materials, or for creating rigid 3-dimenional polymeric structures by in-situ doping and activation of the crosslinker. The disclosed crosslinkers can be activated thermally, by UV radiation or by an electric potential.

Abstract: A series of novel molecular conjugates is disclosed herein, consisting of a photosensitizer moiety chemically bonded to at least one diazirine moiety. Such conjugates react in air and/or water with non-coherent visible light to form singlet oxygen, an energetic species known to be highly toxic to abroad range of pathogens, including bacteria, fungi, microbial biofilms and viruses. Such non-specific cellular damage limits the pathogen's ability to evolve into a resistant form. The diazirine moiety of the conjugate enables the reagent to be adhesively bonded to a plethora of substrates, such as, for example, polymers, non-woven fabrics, surgical masks and gloves, hospital gowns, hospital surfaces (such as counters, mattresses, curtains) medical implants, bandages, wound dressings, or air-filters. The resulting treated substrates act as an effective pathogen-killing barrier, providing protection against the spread of such pathogens to non-infected persons.
