Abstract :
We developed a transient photoinduced voltage measuring system and investigated the photoinduced electron transfer in hetero-structured polyimide (PI) LB films. The photoinduced transient voltage depended on PORPI layers (n), indicating that there are two kinds of electron transfer mechanism. For n>3, the maximum value of the induced transient voltage increased as n increased. We estimated that they were transported in PORPI films at a distance of 2-4 nm
