摘要
紫蓝光有机发光材料在全彩显示和照明领域具有广阔的应用前景。但是该类材料需要宽能隙，因此开发高效的紫蓝色材料是一项巨大的挑战。本文利用10H⁃吩噻嗪5，5⁃二氧化物（2OPTZ）作为弱受体、N⁃苯基⁃2⁃萘胺（PNA）作为供体，设计合成了两个具有D⁃π⁃A型结构的紫蓝色材料，命名为2OPTZ⁃PNA和2OPTZ⁃BP⁃PNA。通过延长给受体之间的π共轭长度，使局域态和电荷转移态被优化，并且薄膜中的绝对量子产率从14%提高到33%。此外，利用2OPTZ⁃BP⁃PNA制备的非掺杂器件呈现紫蓝光（436 nm）发射，半峰全宽为54 nm，色坐标为（0.155，0.046），外量子效率为4.1%。鉴于此，本文提供了一种制备高质量紫蓝发光材料的有效策略。
Abstract
Organic violet-blue luminescent materials have exhibited great potential in full-color displaying and lighting fields. However， it is a huge challenge to develop efficient violet-blue emitters because of the inherently wide energy gap. In this work， two violet-blue emitters with donor （D）-π-acceptor （A） type using 10H-phenothiazine 5，5-dioxide （2OPTZ） as a weak acceptor and N-（2-naphthyl） aniline （PNA） as the donor， namely 2OPTZ-PNA and 2OPTZ-BP-PNA， were designed and synthesized. By extending π-conjugation length between donor and acceptor， local excited states and charge transfer excited states were adjusted， and absolute photoluminescence quantum yields （PLQYs） values in the evaporated film increased from 14% to 33%. Notably， non-doped device based 2OPTZ-BP-PNA exhibits violet-blue light at 436 nm with a narrow full width at half-maximum （FWHM） of 54 nm， Commission Internationale de l’Eclairage （CIE） coordinates of （0.155， 0.046） and external quantum efficiency （EQE） of 4.1%. Given this， our results provide an efficient design strategy for the high-quality violet-blue luminescent materials.
