用于电子应用的新型电致发光聚合物
摘要：
本发明涉及包含式(I)的重复单元的新型聚合物，其中取代基R1、R2、R3、R4、R5、R6和R7的至少一个是基团-(Sp)x1-HEI，其中Sp是间隔基单元，HEI是基团(HEII)，其提高聚合物的空穴注入和/或空穴传输性能；或基团(HEIII)，其提高聚合物的电子注入和/或电子传输性能；或基团(HEIIII)，其提高聚合物的空穴注入和/或空穴传输性能以及聚合物的电子注入和/或电子传输性能，x1是0或1，及其在电子器件中的用途。根据本发明的聚合物具有优异的在有机溶剂中的溶解性和优异的成膜性能。另外，如果根据本发明的聚合物用于聚合物发光二极管(PLEDs)，则可以观察到高载流子迁移率和发射颜色的高温稳定性。
摘要（英）：

The present invention relates to novel polymers comprising a repeating unit(s) of the formula (I) wherein at least one of the substituents R1, R2, R3, R4, R5, R6, and R7 is a group -(Sp)x1-HEI, wherein Sp is a spacer unit, HE1 is a group (HE1), which increases the hole-injection and/or hole-transport properties of the polymers; or a group (HE1II), which increases the electron- injection and/or electron-transport properties of the polymers, or a group (HE1III), which increases the hole-injection and/or hole-transport properties of the polymers and the electron-injection and/or electron-transport properties of the polymers, x1 is 0, or 1, and their use in electronic devices. The polymers according to the invention have excellent solubility in organic solvents and excellent film-forming properties. In addition, high charge carrier mobilities and high temperature stability of the emission color can be observed, if the polymers according to the invention are used in polymer light emitting diodes (PLEDs).
