Photoexcitation dynamics in an alternating polyfluorene copolymer
We have used transient photoinduced absorption on femtosecond to nanosecond time scales as well as delayed fluorescence up to microseconds to study the photogeneration and recombination of charges in thin films of the alternating polyfluorene copolymer poly[2,7-(9,9-dioctylfluorene)-alt-5,5-(4('),7(')-di-2-thienyl-2('),1(') ,3(')-benzothiadiazole)]. We interpret the results using a coupled rate eq
