A pressure dependence of the optical absorption spectra of BF À 4 -doped polypyrrole has been observed at pressures below atmospheric pressure. The two absorption bands at photon energies of 1.2 and 3.0 eV depend on the pressure: a decrease in the high-energy absorption is accompanied by an increase
