Abstract

Summary: Light-driven devices based on reversible change of carrier mobility in semiconducting polymers were investigated. The mobility was altered using a photochromic spiropyran capable of a reversible change of permanent dipole moment and ionization potential. While the latter attribute may result in formation of chemical traps and is more important for matrices with similar ionization potential such as PVK, the former phenomenon results in formation of polar traps and is more pronounced in the case of lower-band-gap materials.
