| Research Abstract |
Conjugated polymer/fullerene heterostructures are designed by spin-coating a conjugated polymer on top of the insoluble film of the fullerene derivative with thermally cross-linkable side chains. With this well-defined D/A heterostructure system, an exciton diffusion length in the conjugated polymer can be estimated from the fluorescence quenching data. The direct observation of charge generation and recombination dynamics at the D/A interface is also performed by transient absorption spectroscopy.
