Description
Summary:碩士 === 國立臺灣大學 === 高分子科學與工程學研究所 === 105 === This study has been separated into four chapters. Chapter 1 is general introduction of high performance polymer, organic-inorganic hybrid materials, and polymer hybrid memory. In chapter 2, aromatic sulfonyl-containing polyether (TPA-PES), polyester (TPA-PETS) and polyimide (TPA-PIS) have been prepared successfully for investigating the relationship between structure of these high-performance polymers with different linkage groups but the same donor and acceptor units and memory properties, and exploring the effects of linkages on memory behaviors of the obtained devices. The different linkages of the three polymers are expected to have distinct dipole moment, linkage conformation, energy band gaps and memory properties. In chapter 3, novel electrochromism (EC) and photoluminescence (PL)-active TPA-CN-CH, TPA-CN-TPE and TPA-OMe-TPE were prepared by direct polymerization. Furthermore, by introducing viologen into electrolyte as a counter EC layer for charge balance, the resulted EFC exhibited notable improvement in reducing oxidation potential and switching recovery time with enhanced fluorescent contrast ratio during pulse on/off multi-cyclic scanning. An OFET memory containing a novel organic polymer TPA-CN-TPE, in which the photo-induced charges can be successfully trapped and detrapped. The luminescent polymer emits intense green emission upon ultraviolet (UV) light excitation and serves as a trapping element of charges injected from the pentacene semiconductor layer. The present study on photo-assisted novel memory may motivate the research on a new type of light tunable charge trapping photo-reactive memory devices.
