液晶モノマーの光重合により誘起される新奇な周期構造

In liquid crystals, special distribution of the refractive index can be modulated by controlling the molecular orientation. Thus, liquid crystals have been applied to the various optical materials such as diffraction grating, reflective device. To improve optical properties of the liquid crystal materials, it is very important to control the molecular orientation precisely. We have found in inducing the formation of periodic structure by using patterned light intensity gradient. Polymer concentration distribution induced by light intensity gradient is important for the formation of periodic structure. In this study, we aimed to investigation the mechanism of the formation of periodic structure.
