Photocurrents in simple polymer systems. II

Large photocurrents have been observed in films of some simple polymers (containing no π‐orbitals), of which poly(vinyl fluoride) is a typical example. Not only are the currents large (up to 10 −5 A/cm 2 ) but also they are capable of being excited by light in the visible wavelength region where absorption by the polymer is too low to be detectable. The results indicate that the effects are electronic, rather than ionic, in nature.
