Phthalocyanine/Polymer Systems for Photochemical Hole Burning Applications

Phthalocyanine (H(2)Pc) in a polymer matrix, for example, polymethyl- methacrylate (PMMA), is suitable for use in photochemical hole burnin applications. One application is a high density information storage system of the type described in U.S. Patent 4,101,976.

A H(2)Pc-PMMA system has the following desirable characteristics: (a) a high hole burning efficiency, (b) a narrow hole width, (c) a broad inhomogeneous 0-0 bandwidth, (d) high thermal stability of the hole, (e) photochemical reversibility, (f) high optical quality at a temperature of 4.2 degrees K, and (g) is a solid at room temperature.
