Paragraph 0144-0146, (2020/10/16)
The invention discloses a substituted 1,3,5-triazine compound, a composition and application thereof. The 1,3,5-triazine compound shown as a formula I is provided by the invention, can be used as an electron transport material and, can be used as an electron acceptor material. The composition that can be used for preparing an electron transport layer or an electron donor material is used as a mainbody material of an electroluminescent device, so that the prepared electroluminescent device has the advantages of relatively high efficiency, relatively long service lifetime and the like. As the 1,3,5-triazine compound is used as an electron transport layer, the composition used as an electron acceptor material and an electron donor material is adopted to construct a light-emitting layer, andthe prepared electroluminescent device has the advantages of higher efficiency, longer service lifetime and the like.

Two new electron-transporting copolyphenylenes P1NH and P2NH possessing balanced charges crucial to emission efficiency of polymer light-emitting diodes (PLEDs) have been synthesized and applied as an electron-transporting layer (ETL). The main chain structure is all para-linkage for P1NH and both para- and meta-linkage for P2NH, with the same pendant electron-withdrawing benzimidazolyl and polar diethanolaminohexyloxy groups. Both copolymers possess excellent thermal stability (Td > 300 °C, Tg > 100 °C) due to their rigid backbones. In addition, the pendant groups effectively lower LUMO (~ ?2.70 eV) and HOMO (~ ?5.70 eV) levels, resulting in improved electron-transporting and hole-blocking capabilities. Multilayer yellow-emitting PLEDs with a configuration of ITO/PEDOT:PSS/SY/ETL/LiF/Al were successfully fabricated by the spin-coating process. The maximum luminance and maximum current efficiency of the P1NH-based device were 12,881 cd/m2 and 10.94 cd/A, respectively, superior to the performance of P2NH-based device (4938 cd/m2, 3.70 cd/A) and the device without ETL (8690 cd/m2, 2.78 cd/A). Current results indicate that P1NH is highly effective in enhancing electron transport and device performance.
