The invention discloses a polyfluorene polymer whose main chain contains non-conjugated units and its preparation method and application. The polymer introduces a type of non-conjugated structural unit into the main chain of polyfluorene to realize the induced production beta-phase. As we all know, polyfluorene polymers are one of the most promising blue light polymers, due to their high fluorescence quantum efficiency, relatively good thermal and electrochemical stability, and easy functionalization at the carbon-9 position of fluorene, etc. β‑relative has a profound effect on film morphology, carrier transport, and device performance. |
