OPTICAL STORAGE USING MATERIALS COMPRISING CHROMOPHORE OLIGOMERS WHICH CAN UNDERGO CYCLOADDITION

摘要

The present invention relates a method for optical storage of information using materials comprising compound having at least two chromophores and a linkage connecting the chromophores. The optical storage method can be effected by use of light having a wavelength of from 100-1600 nm. The compound applicable for the method are typically dimers based on a skeleton made of peptides or amino acids, or alternatively peptide nucleic acid (PNA). The chromophores may thymine, N-(C1-6-alkyl)-thymine, anthracene, acridizinium salts, tetracene, etc.
