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 occurring upon warming the sample. Use in eraseble optical information storage devices and related technologies is discussed.
