Developing of high-quality blue-emitting materials are the most significant for the requirement of both display and lightings. Many phosphorescent blue-emitting materials with high efficiency have been synthesized and studied, but their molecular structure usually contain heavy atoms, which limit the lifetime of the device due to their unstable electric-chemical characteristics. Anthracene is widely used as blue-emitting fluorescence material, which exhibits bipolar transport property, great thermal stability and high PL quantum yield. In this thesis, we design novel anthracene-based materials including two small molecules and one polymer with the concept of asymmetric structure to increase molecular steric hindrance. Thermal and photophysical characteristics of these materials are also analyzed. OLED and PLED device utilizing these materials are also fabricated and studied. Finally, white OLEDs with high color rendering index (>80) have been realized by employing the broad blue-emitting material developed in this thesis. The CIE coordinates can be changed with varying of operating voltages and located on the Plank Locus. Li-Yin Chen 陳俐吟 2014 學位論文 ; thesis 125 zh-TW |

碩士 === 國立中山大學 === 光電工程學系研究所 === 102 === In recent years, many researches in organic light-emitting-diodes (OLEDs) are proposed. Developing of high-quality blue-emitting materials are the most significant for the requirement of both display and lightings. Many phosphorescent blue-emitting materials with high efficiency have been synthesized and studied, but their molecular structure usually contain heavy atoms, which limit the lifetime of the device due to their unstable electric-chemical characteristics.
Anthracene is widely used as blue-emitting fluorescence material, which exhibits bipolar transport property, great thermal stability and high PL quantum yield. In this thesis, we design novel anthracene-based materials including two small molecules and one polymer with the concept of asymmetric structure to increase molecular steric hindrance. Thermal and photophysical characteristics of these materials are also analyzed. OLED and PLED device utilizing these materials are also fabricated and studied. Finally, white OLEDs with high color rendering index (>80) have been realized by employing the broad blue-emitting material developed in this thesis. The CIE coordinates can be changed with varying of operating voltages and located on the Plank Locus.
