A photorefractive dendron compound, a photorefractive dendrimer compound and applications thereof, and more particularly, a photorefractive dendron compound, including a non-linear chromophore containing a tricyanopyrroline-based electron-withdrawing group and a carbazole derivative having excellent charge transport properties, a method of preparing the photorefractive dendrimer compound, a photorefractive device including the photorefractive dendrimer compound, and a method of manufacturing the photorefractive device. In the photorefractive dendrimer compound, dendron has the non-linear optical chromophore and carbazole introduced thereto to thus impart one molecule with both photoconductivity and non-linear optical properties, thereby solving conventional problems caused by poor compatibility between photoconductive material and chromophores in conventional photorefractive material. The dendrimer compound may be applied to bio-imaging techniques thanks to the use of the non-linear optical chromophore, which is sensitive to near infrared light.
