Abstract :
Properties of conducting polymers, especially optical properties, have been found to be strongly influenced by doping of molecular dopants such as C60, aromatic molecules, photo chromic dyes and different structures of conducting polymers, which are interpreted in terms of dynamics of photo-excited electrons, holes and excitons by taking electronic energy states of both conducting polymer and molecular dopants into consideration. Novel characteristics have also been observed upon double doping, superconductivity and ferromagnetism upon doping of Alkali metal and TDAE into C60 doped conducting polymer, respectively. Molecular doped conducting polymers also have exhibited novel junction characteristics such as high efficiency of photovoltaic effects, light sensitive FET characteristics and voltage and its polarity dependent electroluminescence
