CARBAZOLE PHOTOREFRACTIVE MATERIALS

Considerable progress has been made in organic photorefractive materia ls, since the first observation of photorefractive phenomena from orga nic materials. Within recent years, a large number of organic photoref ractive materials, especially amorphous materials, have been developed based on polymeric composites, fully functional polymers and the mult ifunctional chromophore approach. Among these organic photorefractive materials, some of them containing carbazole components as a charge tr ansporting function have been demonstrated to exhibit high performance photorefractive effects. The carbazole building blocks with charge tr ansporting functionality or multifunctions play a very important role in photorefraction and have been widely used in the molecular design a pproach to new organic photorefractive materials. Based on carbazole f unctional building blocks, amorphous multifunctional chromophores, amo rphous monolithic chromophores and amorphous dendrimers have also been developed as new types of organic photorefractive materials. This pap er reviews the recent progress of organic photorefractive materials,es pecially organic photorefractive materials containing carbazole functi onal components.
