“…Thus, polyimide based PR system 21,22 was designed (scheme 3) based upon the fact that porphyrin-electron acceptor (quinones or imide moieties) systems are well known model compounds for photosynthetic processes and they exhibit very interesting charge transfer properties. 23 A high quantum yield of charge separation can be achieved in these systems.…”

Organic photorefractive (PR) materials are a new kind of electrooptic substance that emerged 10 years ago. These are very complicated materials that possess both electrooptic effects and photoconductivity. It is challenging to integrate these properties into a single polymer system that will exhibit this PR effect. This article highlights our efforts in the past nine years in synthesizing and characterizing fully functionalized organic PR materials. I emphasize the lessons we have learned from this research, which may be more valuable to those who are interested in this area. Luping Yu's research focuses on the rational design, synthesis, and characterization of novel functional and multifunctional polymers and molecules. Typical examples of current projects are the following: (1) development of polymerization methodologies, (2) supramolecular assembly of nanostructured materials for nanoelectronics, (3) conjugated diblock copolymers for the formation of self-assembled, nanosized electroactive materials, (4) design, synthesis, and physical studies of photorefractive polymers, and (5) metal-containing functional polymers.

In this article, we review recent progress in the area of photorefractive polymers. Photorefractive (PR) polymers are multifunctional materials which combine photoconductivity and electro‐optic response to show a new phenomenon: light‐induced reversible modulation of the refractive index. Because of their multifunctional features, design, synthesis and preparation of these materials exhibiting high performance is an intellectual challenge. Moreover, numerous applications of photorefractive materials in optical devices have been established using inorganic materials. Utilizing the unique features of organic polymeric materials to prepare useful devices is an engineering challenge. In the past several years, research in this area has gained momentum because numerous new materials which possess better characteristic photorefractive parameters than their inorganic counterparts have been synthesized. Several interesting devices have been presented. Two different approaches have been developed to synthesize and prepare PR polymers, namely composite materials and fully functionalized polymers. Both approaches have had success in identifying new materials and in gaining understanding of the design principles of better materials. This paper discusses these aspects and gives a prospective view about this field.
