Fully functionalized photorefractive polymers incorporating transition metal phthalocyanine and porphyrin complexes as photosensitizers

Photorefractive polymers containing transition metal porphyrin or phthalocyanine complexes (see Figure) are prepared here by Heck polycondensation, and the structural effects of these macrocyclic complexes on the photorefractive performance are investigated. It is reported that the polymers containing Zn complexes exhibit much larger photogeneration quantum yields and optical gains than those containing Cu.
