Photophysics of Single PPV Derivative Polymers

Abstract Conjugated polymers are unique subjects composed of many excitons localized at individual segments. Migration of excitation is strongly correlated with the chain conformation. We studied the PPV derivative polymers, MEH‐PPV and DOO‐PPV, with different chain lengths to probe the relation between the conformation of, and exciton migration in, single polymers. Photo‐quenching of individual conjugated segments was used to provide …
