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 polyp-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.
