Abstract :
Optical properties of conducting polymers such as absorption spectrum, photoluminescence, electroluminescence, photo-magnetic effect, photoconductivity, non-linear optical phenomena and their dynamics change drastically upon doping of small amount of fullerene. Electrical and optical characteristics of junctions based on conducting polymers and fullerenes are also anomalous. It should be mentioned that these unique photophysical properties and their dynamics are dependent on the molecular structure of conducting polymer (non-degenerated polymers such as polythiophene derivatives or degenerated polymers such as polyacetylene derivatives) and also on fullerenes (C60, C70). These novel results are discussed in terms of photoexcitation in both conducting polymers and fullerene, photoinduced excitons, solitons, polarons, also their transfers between conducting polymers and fullerene, capture of carriers by C60, influence of C60 on inter-chain charge transport by taking into account the electronic energy states of conducting polymers and fullerenes.
