| Research Abstract |
We have designed and synthesized a series of photopolymerizable molecules. Thin films were prepared from the synthesized molecules. Solid state polymerization proceeded upon irradiation with ultra-violet light. When the film was irradiated with spatially patterned ultra-violet light, regular surface reliefs with the same period of the patterned light were produced due to the lateral mass transfer from the shaded areas to the irradiated areas. Though the produced surface relief could be erased by heating, the stability of the relief structure was improved as compared to the other surface relief forming materials.
