Efficient near-infrared emission based on donor-acceptor molecular architecture: The role of ancillary acceptor of cyanophenyl

Herein, a new near-infrared (NIR) material, 4-(9-(4-(diphenylamino)phenyl)naphtho[2,3-c][1,2,5]thiadiazol-4-yl)benzonitrile (TPA-NZC), was designed and synthesized with the incorporation of an ancillary acceptor (cyanophenyl) into the donor-acceptor (D-A) molecular backbone of a red emitter TPA-NZP (4,9-diphenylnaphtho[2,3-c][1,2,5]thiadiazole). Compared with TPA-NZP, TPA-NZC exhibits an NIR emission (λmax = 710 nm) with a large redshift, as well as a maintained photoluminescence efficiency (ηPL) of 17% in film. Moreover, the non-doped OLED based on TPA-NZC emitter exhibits an excellent NIR emission at 702 nm with a maximum EQE of 1.2%, while the doped device achieves a deep-red emission at 656 nm with a maximum EQE of 3.2%. This work further verifies the reliability of “hot exciton” and hybridized local and charge-transfer state (HLCT) mechanism, as well as provides a strategy to design a narrow bandgap light-emitting material by introducing cyanophenyl as an ancillary acceptor in D-A systems.

A asymmetric to the [...] organic red fluorescent small molecule material and its in the preparation of the organic electroluminescent device in the application, belongs to the technical field of organic electroluminescent material. This invention utilizes the Suzuki coupling reaction, through the linear conjugated way is connected to the receptor, can realize the high-efficiency light emission, in the preparation of the red light when the doped device, through the use of different parent and optimizing the doping concentration, achieving better effect of the device; in addition, tends to plane the molecular structure of the can through the triplet — triplet annihilation using triplet exciton light-emitting. The invention the resulting compound has very high fluorescence quantum yield, its non-doped red light device the maximum external quantum efficiency of 6.66%, the luminance is 100 and 1000 cd m- 2 The external quantum efficiency is respectively when the 6.51% and 5.11%, efficiency roll-small. Voltage is low, is 2.6 V, device integrated in the organic red fluorescent material is in leading level, to achieving commercial application.
