Abstract
本发明属于OLED技术领域且提供了一种用作主体材料的化合物,具有式(I)的结构;其中m和n分别表示电子给体D和电子受体A的个数且选自1、2或3,p和q分别选自0、1或2;L1、L2和电子给体D各自独立地选自烷基、环烷基、杂环基、芳基、杂芳基、稠芳基或稠杂芳基;电子受体A选自含氮杂环、含氰基、含磷氧基的取代基或三芳基硼类取代基。本发明化合物中的D‑(π)‑σ‑(π)‑A结构具有双极性,σ键可有效打断电子给体D与电子受体A之间的分子内电荷传输,使激发态限制为D或A的片段内的局域激发态,因而使化合物具有小的激发态偶极矩,当其用作发光层主体材料时,可有效降低蓝光材料的效率滚降,提升发光亮度和发光效率。

背景技术
有机电致发光器件(OLED)作为新一代显示技术,具有超薄、自发光、视角宽、响应快、发光效率高、温度适应性好、生产工艺简单、驱动电压低、能耗低等优点,已广泛应用于平板显示、柔性显示、固态照明和车载显示等行业。
按发光机理,OLED发射的光可以分为电致荧光和电致磷光两种。荧光是单重态激子的辐射衰减跃迁所发射的光,磷光则是三重态激子辐射衰减到基态所发射的光。根据自旋量子统计理论,单重态激子和三重态激子的形成概率比例是1:3。荧光材料内量子效率不超过25%,外量子效率普遍低于5%;电致磷光材料的内量子效率理论上达到100%,外量子效率可达20%。1998年,我国吉林大学的马於光教授和美国普林斯顿大学的Forrest教授分别报道了采用锇配合物和铂配合物作为染料掺杂入发光层,第一次成功得到并解释了磷光电致发光现象,并开创性的将所制备磷光材料应用于电致发光器件。
由于磷光重金属材料有较长的寿命(μs),在高电流密度下,可能导致三线态-三线态湮灭和浓度淬灭,造成器件性能衰减,因此通常将重金属磷光材料掺杂到合适的主体材料中,形成一种主客体掺杂体系,使得能量传递最优化,发光效率和寿命最大化。在目前的研究现状中,重金属掺杂材料商业化已成熟,很难开发可替代的掺杂材料。因此,研发新的磷光主体材料成为了一个新的方向。
发明内容
有鉴于此,本发明提供一种具有D-(π)-σ-(π)-A结构的化合物,所述化合物具有式(I)所示的化学结构:
其中,D表示电子给体,A表示电子受体;其中,m和n分别表示电子给体D和电子受体A的个数且m和n分别选自1、2或3;p和q分别表示L1和L2的个数且分别选自0、1或2;
L1和L2各自独立地选自单键、取代或未取代的C1-C20亚烷基、取代或未取代的C3-C20亚环烷基、取代或未取代的C3-C20亚杂环基、取代或未取代的C6-C40亚芳基、取代或未取代的C4-C40亚杂芳基、取代或未取代的C10-C60的亚稠芳基或取代或未取代的C10-C60的亚稠杂芳基中的至少一种;当p或q为2时,各个L1或L2之间可以相同或不同;
电子给体D选自取代或未取代的C1-C20烷基、取代或未取代的C3-C20环烷基、取代或未取代的C1-C20烷氧基、取代或未取代的C3-C20杂环基、取代或未取代的C6-C40芳基、取代或未取代的C4-C40杂芳基、取代或未取代的C10-C60的亚稠芳基、取代或未取代的C10-C60的亚稠杂芳基、取代或未取代的C12-C40的咔唑基及其衍生物基团、取代或未取代的C12-C40的二苯胺基及其衍生物基团、C12-C40的吖啶基及其衍生物基团中的至少一种;当m为2或3时,各个电子给体D之间可以相同或不同;
电子受体A选自含氮杂环类取代基、含氰基类取代基、三芳基硼类取代基和含磷氧基类取代基中的至少一种;当n为2或3时,各个电子受体A之间可以相同或不同。
本发明的化合物具有D-(π)-σ-(π)-A结构,是一种双极性材料,可以替代现有传统的D-π-A骨架结构。传统的D-π-A双极性材料具有很强的分子内电荷传输,导致大的偶极矩μs,而本发明的化合物中的D-(π)-σ-(π)-A结构同样具有双极性,中间的σ键可以有效打断电子给体D与电子受体A之间这种传输,使得激发态限制为电子给体D或者电子受体A的片段内的局域激发态,因而使化合物具有小的激发态偶极矩,当其用于OLED器件的发光层的主体材料时,可以有效降低蓝光材料的效率滚降,提升发光亮度和发光效率。
本发明的化合物用作电致发光器件中的主体材料,具有较高的三线态能级ET和较大的分子密度,较高玻璃化温度和分子热稳定性,有效提高载流子的平衡迁移,扩宽激子复合区域,有效提高光的取出效率,使得器件的发光效率(EQE)和寿命有了很大提升,在电致发光器件技术领域中可以得到很好的应用。
