Abstract
Crosslinked polymers whose performance is based on nondiffusive, quantum-amplified photoisomerzation of Dewar benzene derivatives, which exhibit remarkable information-storage properties, were reported. It is observed that materials containing electron-deficient Dewar benzene derivatives exhibit higher sensitivity as compared to materials that contain electron-rich Dear benzene derivatives. A low adsorption cross-section at the recording wavelength of 407 nm ensures homogeneous recording throughout the depth of the recording media. Facile and inexpensive thermal curing of photosensitive mixture by free-radical-initiated cross-linking is shown to afford freestanding polymeric films under a solventless processing technique that are transparent and colorless with thickness of up to several millimeters.
