文摘

The synthesis and characterization of a series of copolymers consisting of polyethylene (PE) andperylenediimide (PERY) dyes is described. The synthetic route comprises metathesis polymerization of cis-cyclooctene (COE) and PERY substituted with two allyl groups. This enables incorporating PERY dye moleculesinto an unsaturated polycyclooctene (PCOE) chain. Subsequent hydrogenation of the PCOE-PERY copolymeraffords a high molecular weight PE-PERY copolymer. Ring formation occurs during the metathesis polymerization,but can be suppressed by increasing the initial monomer concentration in accordance with Jacobsen-Stockmayertheory, giving access to predominantly linear PE chains with PERY incorporated in the polymeric chain. Opticalcharacterization of the PE-PERY copolymer with UV-vis absorption and photoinduced absorption spectroscopyreveals that the optical and electronic properties of the PERY moieties are not significantly affected by incorporatingthem into the polymer chain.
