    Highly Efficient Red Phosphorescent Osmium(II) Complexes for OLED Applications
    摘要:
    The nonionic, red-emitting complexes [Os(fppz)(2)L-2] (L = PPh2Me (1), PPhMe2 (2)) and [Os(bptz)(2)L-2] (L = PPh2Me (3)) were synthesized, showing highly intense red phosphorescent emission in CH2Cl2 solution at lambda(max) 617, 632, and 649 nm, respectively. The electroluminescent properties of these compounds on OLEDs showed promising device efficiencies required for future OLED applications.

    本文介绍了荧光化合物及其用途,以及包括这些化合物的有机发光二极管(OLED)在内的装置。感兴趣的化合物包括:其中A是Os或Ru。阴离子螯合色团N{circumflex over ( )}N是通过将至少含有两个氮原子的五边形环结构与一个六边形吡啶类型的片段通过直接碳-碳键连接而形成的。L是一个中性给体配体;典型的例子包括羰基、吡啶、膦、砷和异氰酸酯;两个中性的L也可以组合成所谓的螯合配体,如2,2′-联吡啶、1,10-邻菲啰啉和N-杂环卡宾(NHC)配体,或者是双齿膦配体,如1,2-双(二苯基膦基)乙烷、1,2-双(二苯基膦基)苯。L可以占据顺式或反式位向。当L占据反式位置时,首选结构包含NAN的六边形片段以及其位于反向位置的五边形片段,相对于第二个NAN色团的对应物。当L占据顺式位置时,首选结构由N{circumflex over ( )}N色团的五边形单元组成,位于L的对面。X1、X2和X3独立地是C或N;当X2为N时,省略R;当X3为N时,省略R2;R1为H、C1-C8烷基、C1-C8取代苯基或C1-C4全氟烷基;R2为H、F或氰基取代基;X4为C或N;当X4为N且R3和R4未与X4连接时,X4可以位于六边形环的任何位置;R3为H、甲基或C1-C3小烷基;R4为H、甲基或C1-C3小烷基;或者R3和R4共同形成具有结构的额外共轭单元。

    Triosmium cluster complexes [Os3(CO)8(fppz)2] (2a) and [Os3(CO)8(fptz)2] (2b) bearing two 2-pyridyl azolate ligands were synthesized in an attempt to establish the reaction mechanism that gives rise to the blue-emitting phosphorescent complexes [Os(CO)2(fppz)2] (1a) and [Os(CO)2(fptz)2] (1b) [(fppz)H = 3-(trifluoromethyl)-5-(2-pyridyl)pyrazole; (fptz)H = 3-(trifluoromethyl)-5-(2-pyridyl)triazole].

    A total of three distinctive main group and transition metal complexes containing the 2-pyridyl pyrazolate (pypz) ligand were prepared, namely, [B(C6F5)(2)(pypz)] (1), [Ru(CO)(2)-(pypz)(2)] (2), and [Os(CO)(2)(pypz)(2)] (3), where (pypz)H = 3-trifluoromethyl-5-(2-pyridyl)pyrazole. Single-crystal X-ray diffraction studies were carried out on complexes 2 and 3, revealing octahedral coordination geometry with two CO ligands located at cis dispositions. While the pypz ligand arrangement for complex 2 is in cis-(N-py,N-py) and trans- (N-pz,N-pz), complex 3 reveals a different configuration, cis-(N-pz,N-pz) and trans-(N-py,N-py) (N-py for pyridine-N and Npz for pyrazolate donor sites). Similar to that of the in-situ-prepared pypz anion, the boron complex [B(C6F5)(2)(pypz)] (1) exhibits a strong emission centered at 380 nm, which is unambiguously assigned to fluorescence derived from the S-1(pipi*)-->S-0 transition. In contrast to the nonluminescent behavior for Ru complex 2, the Os complex 3 displays unique, strong room-temperature phosphorescence, showing vibronic progressions at 430, 457, and 480 rim. The remarkable differences in photophysical properties were rationalized by a combination of pi-electron accepting CO ligand, relative pypz orientation, and heavy-atom-enhanced spin-orbit coupling effects.
