  By fusing an electron-deficient ring system with the phenyl ring of a 2-phenylpyridine (ppy)-type ligand, a new and synthetically versatile strategy for the phosphorescence color tuning of cyclometalated iridium(III) and platinum(II) metallophosphors has been established. Two robust red electrophosphors with enhanced electron-injection/electron-transporting features were prepared by using an electron-trapping fluoren-9-one chromophore in the ligand design. The thermal, photophysical, redox and electrophosphorescent properties of these complexes are reported. These exciting results can be attributed to a switch of the metal-to-ligand charge-transfer (MLCT) character of the transition from the pyridyl groups in the traditional IrIII or PtII ppy-type complexes to the electron-deficient ring core, and the spectral assignments corroborate well with the electrochemical data as well as the time-dependent density functional theory (TD-DFT) calculations. The electron-withdrawing character of the fused ring results in much more stable MLCT states, inducing a substantial red-shift of the triplet emission energy from yellow to red for the IrIII complex and even green to red for the PtII counterpart. Electrophosphorescent organic light-emitting devices (OLEDs) doped with these red emitters fabricated by using vacuum evaporation technique have been realized with reasonable performance.

  通过将一个缺电子的环体系与2-苯基吡啶（ppy）型配体的苯基环结合，建立了一种新的合成多样性策略，用于调节环金属化的铱（III）和铂（II）金属磷光体的磷光颜色。通过在配体设计中使用电子捕获的芴-9-酮染料，制备了两种具有增强电子注入/电子传输特性的坚固红色电致磷光体。这些复合物的热性能、光物理性质、氧化还原特性和电致磷光特性得到了报道。这些激动人心的结果可以归因于金属-配体电荷转移（MLCT）特性从传统的IrIII或PtII ppy型络合物中的吡啶基转移到缺电子的环核心的变化，光谱归属与电化学数据以及时间依赖密度泛函理论（TD-DFT）计算结果很好地相符。连接的环的吸电子特性导致更稳定的MLCT态，使IrIII络合物的三重态发射能量从黄色显著红移到红色，而PtII对应物则从绿色红移到红色。使用真空蒸发技术制造的掺杂这些红色发射体的电致磷光有机发光二极管（OLED）已实现了理想的性能。
