Photoelectric Properties of Film Composites Based on Poly(Vinyl Butyral) and Heterometallic Complexes.

Photosensitive polymeric film composites based on nonphotoconducting poly(vinyl butyral) doped with heterometallic Cu/M complexes (M = Ca, Sr) were synthesized and investigated. These composites possessed photoconducting and photovoltaic properties and electron-type photoconductivity. The greater photocurrent for composites with complexes having shorter distances between the nearest Cu metal centers was attributed to the greater probability of electron transfer between these centers.
