Abstract
Highly sensitive polarized absorption measurement by the optical wave-guide detection system was proposed to analyze the optical characterestics of photoresponsive polymer thin films. The extinction coefficients of specific ion-pair charge-transfer complexes between polymeric 4, 4′-bipyridinium and tetrakis[3, 5-bis(trifluoromethyl)phenyl]borate film were estimated by this system. The thickness of these films estimated from observed OWG absorbance almost coincided with that by the ellipsometry. The accuracy of this analysis was supported by these results.
