| Summary: | 碩士 === 國立臺灣海洋大學 === 光電科學研究所 === 100 === There are two topics in this thesis. First, we discussed thermal cross-linkable molecules that can be polymerized through thermal curing to form polymers. Second, we used Au-Cu clusters molecules as dopant to fabricate OLEDs.
In first part, we reported a series of crosslinkable materials with styryl moiety as peripheral pendent groups, giving the resulting polymer with high solvent resistance which can facilitate the deposition of subsequent layers through solution-processing. We employed these thermally polymerized polymers as hole-transport layers in fluorescence and phosphorescence OLEDs. They showed comparable OLEDs performance, giving more flexibility on material selection for future OLEDs applications, especially solution-processed ones.
In second part, we used Au-Cu clusters as emitters blend with TCTA by solution process to fabricate OLEDs. Among them, the best performance is obtained in the emitter with TCTA: Au10 ratio of 5:2. The EQE reached 4.8 %(13.1 cd/A) which is compared with fluorescent material in OLED devices.
