| 제목 | New Photopolymer Film Having Chalcone Moiety And Their Excellent Alignment For Liquid Crystals |
| 초록 | Photosensitive polymers with chalcone groups have been examined in the applications of photoalignment film. Alignment behavior of LC molecules would be simply enhanced by the liquid crystalline polymer surface where mesogenic groups having similar chemical structure to that of the LC molecules existed. In addition, using reactive mesogen(RM) instead of LCs has the simple and keeps advantages of photo-alignment, such as high alignment uniformity, easiness of alignment control, and precise patterning. In this paper, new photopolymer with chalconyl groups, PM, was synthesized. The photopolymer have high sensitivity and superior photo-alignment capability to very low UV exposure energy. Especially, the higher sensitivity of LC alignment capability to low UV energy is essential to shorten exposure time in photo-alignment process for practical application to the retarder films. |
