Photoinduced Electron Transfer in Binary Blends of Conjugated Polymers.
Abstract
We report observation of photoinduced electron transfer between two n-conjugated polymers in binary mixtures. Picosecond transient absorption and fluorescence spectroscopies of mixtures of n-type (electron accepting) poly (benzimidazobenzophenanthroline ladder) (BBL) and p-type (electron donating) poly (p- phenylene benzobisthiazole) (PBZT) or poly(p-(2-hydroxy)-phenylene berizobisoxazole) (HPBO) evidence intermolecular electron transfer when BBL is selectively photoexcited. The results suggest that blends of n-conjugated polymers are supramolecular materials which have novel features such as delocalized radical ion pairs or diion pairs, - novel properties, and- implications for organic p-n junction devices, photodiodes, photovoltaic cells, photoreceptors, and molecular electronic devices.
