一系列發藍光芳香族聚酯經由1-[N,N-di(4-carboxyphenyl)amino]naphthalene此種二酸分別與多種二酚在吡啶和氯化鋰的介質中藉由DPCP活化來進行直接聚合反應。這一系列新型具萘胺發光側鏈基團之芳香族高分子聚酯之合成與基本特性、光致發光及電化學性質已被研究。所有的高分子聚酯不僅在極性非質子型溶劑中有好的溶解性及出色的薄膜成形能力,並且展現出高的玻璃轉換溫度,好的熱穩定性及較低的HOMO能階。如此,這些含萘胺的高分子由於具有適當的HOMO能階、出色的熱穩定性和螢光量子效率等特性,也許能被廣泛的應用在P-LED當電洞傳輸層和藍光發光材料。
A newly series of blue photoluminescent aromatic polyesters (polyarylates) were synthesized from 1-[N,N-di(4-carboxyphenyl)amino]naphthalene with various bisphenols by the diphenylchlorophosphate (DPCP) activated direct polycondensation in a medium of pyridine and lithium chloride. The synthesis, basic characterizations, photoluminescence and electrochemical properties of this series of novel polyarylates bearing pendent naphthylamine chromophores were investigated. All polymers not only had good solubility in many polar aprotic solvents and excellent thin-film-forming ability, but also exhibited high Tg values, good thermal stability and lower HOMO level. Thus, these naphthylamine-containing polyarylates may be widely applied in P-LED as hole-transporting layer and blue light-emitting materials due to their proper HOMO level, excellent thermal stability and fluorescence quantum efficiency.
