  供体互锁分子设计，用于深蓝色热激活延迟荧光发射体中的荧光状窄发射。

  摘要：

  通过管理TADF发射器的分子结构，开发了具有窄发射光谱的深蓝色热激活延迟荧光（TADF）发射器。深蓝色TADF发射器设计为在分子的中心区域显示出较大的位阻，并在单重态-三重态的能量间隙较小。深蓝色TADF发射器的分子工程设计使得能够制造深蓝色TADF器件，其半峰全宽仅为48 nm，量子效率为14.0％。深蓝色TADF器件的半峰全宽与常规荧光器件相似，而量子效率却提高了两倍多。

  The present invention relates to an organic mixture and an application thereof in organic electronic devices. The organic mixture comprises a spirofluorene organic compound containing a fused heterocyclic ring and an aromatic fused heterocyclic organic compound containing an electron-donating group. A combination of the two materials may be used as a host material of a phosphorescent organic light-emitting diode (OLED), which may use the energy of excitons and balance the charge transport to the greatest extent and which may effectively reduce the concentration of excitons and the operating voltage of a corresponding device, thereby effectively improving the efficiency and service life of the related electronic device in order to provide an effective solution for improving the overall performance of an organic electronic device.

  Disclosed are a transition metal complex, a polymer, a mixture, a composition and the use thereof, wherein the transition metal complex has a structure of the general formula as shown in formula (1): The transition metal complex has a novel structure, and is an iridium (III) complex comprising rigid cycloalkyl groups. Since this type of auxiliary ligand increases the rigidity and symmetry of a molecule, the rigidity of a molecule is increased relative to a common ligand without the cycloalkyl groups, and as such, the whole complex has better chemical, optical, electrical and thermal stabilities. At the same time, since the modification occurs on the auxiliary ligand, the effect on the wavelength of the luminous maximum peak caused by a main ligand is relatively low, and therefore, a saturated luminous color may be retained. Therefore, the use of the transition metal complex according to the present invention in OLEDs, in particular as a doping material of a luminous layer, can provide a relatively high luminous efficiency and a relatively long lifetime of the device.
