Abstract
Optical absorption and reflection measurements are carried out on undoped and AsF5 doped films of “poly(4,4′-biphenylylene)” over a wide wavelength region (300–50000 cm−1). In the doped polymer, the free carrier absorption band appears in the IR region and the dc conductivity is estimated from the observed spectrum. The obtained value (σ0=376 S cm−1) is two orders of magnitude larger than the value (σ0=2 S cm−1) observed by the conductivity measurement. The discrepancy may be due to the existence of many cracks on the films.Keywords
