含卡唑、芴及苯賽雙唑之聚苯基乙烯系高分子衍生物之有機高分子發光二極體

Abstract

In this thesis, a series of carbazole/ fluorene/ benzothiadiazole-containing PPVs system polymers was synthesized and the relationships between chemical structure design and thermal stability, optical properties, electro-chemical properties, and device performance are characterized. At first, we synthesized a novel carbazole/ fluorene containing monomer as a blue emitter, and copolymerized with a red emitter, MEHPPV. We also synthesized a MEHPPV homopolymer as comparison. We also synthesized a benzothiadiazole-containing monomer to copolymerize a tricopolymer with various ratios to obtain the relationships between chemical structure design and thermal stability, optical properties, electro-chemical properties or device performance.
