“…To minimize phase separation and, simultaneously, utilize the advantage of orientational enhancement, Yu and coworkers have designed and synthesized (Scheme 16) a simple, small molecular system (132) that connects covalently an NLO chromophore to a 3-alkylsubstituted oligothiophene. 128 The oligothiophene moiety plays a dual role as both the photocharge generator and the charge transporter while the electrooptic effect can be generated by aligning the dipoles of the NLO chromophore (D±A stilbene moiety) under an applied electric ®eld. Furthermore, an amorphous ®lm of this material can be prepared by sandwiching it between two indium tin oxide (ITO) glass slides.…”

“…Apart from their excellent processibility and transparency, the major advantage of small molecular systems is that they are easy to purify and benefit significantly from the orientational enhancement associated with low-T g materials. 94,95) Recently, we synthesized a simple, small molecular system that contains a 3-alkyl-substituted oligothiophene molecule covalently connected to a NLO chromophore. The molecule contains all the functions necessary to show the PR effect.…”

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.
