Abstract: The polyaniline family of polymers exhibits properties that allow for the storage of optical information Photoexcitation of several forms of polyaniline results in long-lived changes in the absorption spectra, associated with trapped charged defect states. These new absorptions exhibit long lifetimes at low temperature (below -250 K), with erasure occuring upon warming the sample. Use in erasable optical information storage devices and related technologies is discussed.
