Description
技术领域
本发明涉及磷光发光材料领域,尤其涉及一类含有五元杂芳环的四齿环金属铂(II)配合物磷光材料。
背景技术
OLED即有机发光二极管(Organic Light-Emitting Diode)或有机发光器件(Organic Light-Emitting Device),又被称为有机电致发光器件(OrganicElectroluminescent Device)。有机电致发光是指在顺向偏压电场的作用下有机小分子发、金属有机配合物分子或聚合物分子发光材料将电能直接转化为光能的一种发光现象。一般情况下,OLED器件的阳极和阴极之间至少要有一层有机层。器件在电流所衍生的顺向偏压作用下,阳极和阴极分别向有机层注入空穴和电子,空穴和电子分别向阴极和阳极方向移动。当两者在移动中相遇、结合,即形成电子-空穴对(electron-hole pair),从而使有机分子受到激发成为激发态分子。若受激电子和基态电子自旋方向相同,则为单线态(singlet)分子;反之,若两电子自旋方向相反,则称为三线态(triplet)分子。处于激发态的分子如果以辐射方式释放能量回到基态就会发出光,由单线态分子释放的光为荧光(Fluorescence),三线态分子所释放的光为磷光(Phosphorescence);此外亦可通过非辐射的方式释放能量回到基态而发热。
OLED是自主发光器件,无需背光源,具有响应速度快、驱动电压低、发光效率和分辨率高、对比度高、视角广等特点,此外它能以廉价的玻璃、金属甚至柔性的塑料为基板,因此还具有成本低、生产工艺简单、可进行大面积生产等优点,已成为新一代的全彩显示和照明技术,在手机、电脑、电视、数码相机、GPS、可弯曲和折叠等电子产品以及平面固态照明领域具有广阔而巨大的应用前景。
早期的OLED由于发光效率极低、驱动电压高、寿命差等原因,使之研究发展异常缓慢。直到1987年,美国柯达公司的华裔科学家邓青云和S.A.VanSlyke采用真空蒸镀技术,以8-羟基喹啉铝配合物(Alq3)为发光材料、三芳胺类化合物作为空穴传输层、铟锡氧化物(ITO)为透明阳极、美铝合金为阴极制得了纳米级的高质量超薄膜,实现了驱动电压低、效率和亮度高的有机电致发光器件(Appl.Phys.Lett.1987,51,913),在OLED领域完成了开拓性的工作;1990年,英国剑桥大学卡文迪许实验室的J.H.Burroughes等人又成功实现了以有机共轭高分子聚合物作为发光材料的OLED器件(Nature,1990,347,539)。自此在世界范围内开启了有机电致发光材料和器件研究的热潮。其中发光材料的设计、合成和开发是整个OLED领域的重中之重,对器件的性能起着决定性的影响。早期器件所采用的发光材料主要为有机小分子荧光材料,而自旋统计量子学表明荧光材料的理论内部量子效率仅为25%。直到1998年美国普林斯顿大学的Forrest教授和南加州大学的Thompson教授发现了室温下金属有机配合物分子材料的磷光电致发光现象,利用重金属原子的强自旋轨道耦可以有效促进电子由单线态到三线态的系间蹿越(ISC),从而OLED器件可以充分利用电激发所产生所有单线态和三线态激发子(exciton),使发光材料的理论内部量子效率可达到100%(Nature,1998,395,151)。至此使有机发光材料的研究进入了一个全新的时期。
之后,人们对发光材料的研究重点转移到了重金属钌(II)、铑(II)、铱(III)、金(I)及铂(II)有机配合物磷光材料上,尤其是有机铱和铂配合物的光物理和器件性能表现较为突出(参见Dalton Trans.2009,167;Chem.Soc.Rev.2010,39,638;Chem.Soc.Rev.2013,42,6128;J.Mater.Chem.C,2015,3,913及其中的参考文献)。环金属钌(II)、铑(II)、铱(III)配合物中心离子为d2sp3杂化,配合物结构为八面体构型,一般较为稳定,但是较难同时与两个三齿配体结合,而与四齿配体的配位数不匹配,故所用配体多为双齿配体,结构单一,不利于进一步修饰,制约了这类磷光材料在光物理和器件性能上的进一步发展。早期研究的环金属铂(II)配合物磷光材料多为含有双齿配体和三齿配体的金属有机分子。双齿环金属铂(II)配合物刚性较低,两个双齿配体易扭曲、振动而使其磷光量子效率低下(Inorg.Chem.2002,41,3055);虽然含有三齿配体的环金属铂(II)配合物由于分子刚性增强可以提高金属配合物的磷光量子效率(Inorg.Chem.2010,49,11276),但是所含有的第二个配体(如Cl-、苯氧基负离子、炔负离子、卡宾等)会使配合物的化学稳定性降低,故双齿和三齿环金属铂(II)配合物磷光材料均不利于制备稳定而高效的OLED器件。而环金属铂(II)配合物中心金属离子是dsp2杂化,铂(II)配合物分子为平面四边形构型,易于和四齿配体配位形成稳定的刚性分子。最近,美国亚利桑那州立大学的Jian Li教授课题组设计合成了一系列的含有四齿配体的环金属铂(II)配合物磷光材料,极大地推进了此类磷光材料在OLED领域中的发展和应用。四齿环金属铂(II)配合物磷光材料的优势在于:(1)环金属铂(II)配合物分子为平面四边形构型,易于和四齿配体进行配位,可以通过金属化反应一步合成,易于纯化,不会产生铱(III)基配合物中的facial和meridional异构体;(2)分子刚性强,磷光量子效率高,甚至达到100%;(3)可以有效提高分子的化学稳定性和热稳定性,利于其在OLED器件中的应用;(4)配体结构易于修饰和调节,进而配合物分子最高占有轨道(HOMO)、最低非占有轨道(LUMO)及三线态的能级,从而调控分子的光物理性质,如发光颜色、颜色纯度、激发三线态寿命等,易于设计合成红、绿、蓝等具有各种颜色各种发射光的磷光分子,以满足其在全彩显示和照明领域的要求。近年来对四齿环金属铂(II)配合物的研究逐渐在铂(II)基磷光材料领域占据主导地位,部分器件性能甚至优于铱(III)基磷光材料掺杂的OLED器件,使其在OLED全彩显示和照明领域有着巨大的应用前景(Adv.Mater.DOI:10.1002/adma.201601861;Angew.Chem.Int.Ed.2013,52,6753;Inorg.Chem.2013,52,7344;Adv.Mater.2014,26,2931;Adv.Mater.2014,26,7116;Org.Electron.2014,15,1862;Adv.Funct.Mater.2014,24,6066;ACSAppl.Mater.Interfaces 2015,7,16240;Adv.Opt.Mater.2015,3,390;US 9385329;US9224963)。
目前已报导并合成的四齿环金属铂(II)配合物的配体大多为含有吡啶、咪唑、吡唑、N-杂卡宾、喹啉、异喹啉的功能团,而对于含有2H-1,2,3-三唑、1H-1,2,3-三唑、1,3,4-噁二唑、噁唑及噻唑的四齿环金属铂(II)配合物则极为少见,而其和咔唑-吡啶形成配体的四齿环金属铂(II)配合物磷光材料则尚未见报道,对于此类磷光分子的光物理和光化学性质也研究甚少。虽然人们对环金属铱(III)和铂(II)配合物磷光材料的研究正在日益深入,但是OLED领域依然存在这诸多问题,比如发光颜色纯度高的磷光材料、饱和而高效的红光材料、含氟蓝光磷光材料的稳定性问题、稳定而高效的蓝光磷光材料等问题,能够满足商业化需要的磷光发光材料依然及其有限。因此开发新的磷光发光材料依然具有举足轻重的意义。
