Abstract
p-Phenylene dihydroxyphenylbenzoxazole (PPHBO) compound was synthesized with t-butoxycarbonyl (t-Boc)-protected benzoxazole moiety and 2,5-dihexyloxybenzene-1,4-diboronic acid, followed by cleavage of the t-Boc group, in which PPHBO would be used for optical recording because of its unique photophysical properties. The optical properties of PPHBO were investigated in solution and in the solid state in terms of molecular conformation. The intramolecular proton transfer in PPHBO was used for fluorescence patterning. The solid film (mixed with PVA) on silicon wafer showed fluorescence quenching under UV irradiation, which was used for photo-triggered recording and erasing.

광기록 저장재료로서 벤족사졸을 사용하기 위하여 벤족사졸 유도체(PPHBO)를 2,5-dihexyloxybenzene-1,4-diboronic acid와 t-butoxycarbonyl(t-Boc)기로 치환된 벤족사졸을 사용하여 합성하였으며, 이의 광학적 성질을 측정하고, UV 조사에 의해 형광색이 변화하는 특성을 이용하여 형광 패터닝을 수행하였다. t-Boc기가 보호/탈보호된 벤족사졸 화합물의 용액에서와 고상에서 광학적 성질을 분자 conformation 관점에서 분석하였으며, 이를 기반으로 이화합물의 분자내 양성자 이동 특성을 이용하여 형광 패터닝에 사용하였다. 벤족사졸 화합물을 PVA와 혼합하고, 실리콘 웨이퍼를 기판으로 하여 UV 조사에 의하여 형광이 변화하는 특성을 이용하여 UV 광기록 및 삭제를 실시하여 광기록 저장재료로서 활용성을 연구하였다.
