- 論文の詳細を見る
Transient photoconductivity measurements have been performed on polyaniline(PAN), poly(2-methoxyaniline)(PMA)and poly(2-fluoroaniline)(PFA)films by means of the time-of-flight technique. The effect of prosessing solvents such as N-methylpyrrolidinone(NMP)and dichloromethane on the nature of transient photocurrent signals is discussed. In the NMP-cast PAN, PFA and PMA films, the photocurrent was composed of only short-lived components, which did not show the sign of transit time. On the other hand, the PMA film cast from dichloromethane showed a long-lived component of photocurrent with the presence of a field-dependent kink due to the transit time. PAN and PFA are least soluble in dichloromethane. The room-temperature hole mobility of PMA cast from dichloromethane solution has been found to be 1.2×10^<-5>cm^2/V・s at an applied field of 1.0×10^6V/cm.
