Abstract

Photochemical hole burning (PHB) is attracting an interest as a means for frequency-domain optical storage. Besides, PHB is expected as a probe for understanding the dynamic behavior in polymers at low temperatures. The low-temperature properties of polymers have been investigated mechanically and dielectricly for many years. In the present study, excursion temperature dependence of hole profile for chromophore/polymer systems is investigated, and is compared with mechanical and dielectric behavior of polymers, so as to get hold of the relationship between relaxation properties and chemical structure of polymers.
