제목 | Synthesis of PVK Containing Ru-complexes as a Photosensitizer and Characterization of its Photoconductive Properties |
초록 | The photorefractive(PR) effect is defined as the spatial modulation of the index of refraction in an electro-optically active material due to the redistribution of charge carriers photogenerated under uniform illumination. For effective photorefractivity, materials must exhibit high photogeneration efficiency, good photoconductivity and effective electro-optical property. In this works, PVK-bonded Ru(bpy)2(m-COOH)(PF6)2 was synthesized by the Friedel-Crafts reaction of PVK with Ru(bpy)2(m-COOH)(PF6)2. The Ru complex was covalently attached to PVK in order to overcome the aggregation problem of doping system and raise the molar ratio of Ru complex. Photogeneration efficiency and photoconductivity of the PVK-Ru complex were obtained by the xerographic discharging method and the dc photocurrent measurement, respectively, at the wavelength of 532nm. The photorefractive composites were prepared by mixing PVK-Ru complex with liquid crystal and their photorefractive properties were characterized by two-beam coupling measurement. |
