Abstract

The reversible photoisomerization and thermal isomerization of azobenzene-based groups covalently bound to the polymers systems were investigated in the solution. The thermal Z-E isomerization rate could be obtained by varying the substituent of azobenzene or copolymer composition. This change of orientation of azobenzene groups may be suitable for optical storage. In principle the orientation change is permanent, but it can be easily erased by heating, on which the original random orientation is largely restored.
