An electronic transmission material, preparation method and its application

The invention relates to an electron transport material, and a preparation method and application thereof. The electron transport material uses aryl group as the center, wherein one side is connected with a naphthyridine group with electron transport property, and the other side is connected with a group different from naphthyridine with electron transport property, thereby constituting an unsymmetrical structure. The two sides of the aryl group are connected with different groups, thereby destroying the molecular symmetry, further destroying the molecular crystallinity and avoiding the intermolecular aggregation; and thus, the electron transport material has favorable film-forming property. Most groups in the molecule are rigid groups, thereby enhancing the heat stability of the material. Meanwhile, the aryl group is connected with the groups with electron transport property, so that the material has favorable electron transport capacity and hole barrier capacity, and can be used as an electron transport layer for organic electroluminescent devices.

Bipolar anthracene derivatives containing hole- and electron-transporting moieties for highly efficient blue electroluminescence devices

A series of bipolar anthracene derivatives containing hole-transporting triphenylamine and electron-transporting benzimidazole moieties were synthesized and characterized. These compounds possess high thermal properties and quantum yield in toluene solution but their photoluminescence spectra are sensitive to the polarity of the solvent. Three types of devices were fabricated to investigate their electron-transporting and hole-transporting as well as light-emitting properties. The electroluminescence spectra for the three derivatives B1, B3 and B4 show that they emit blue light, while the B2-based devices produced white light at a low current density because of the electromer formation. Moreover, a single layer OLED device for B4 exhibited a current efficiency of 3.33 cd A-1 with a pure blue color of CIE (x,y) of (0.16, 0.16) at 20 mA cm-2 and a maximum brightness of 8472 cd m-2 at 8.7 V.
