摘要：
To evaluate the effect of chromophore location on electroluminescent performance, three types of block copolymers consisting of polyfluorene and polytriarylamine with benzothiadiazole (BT) moieties were synthesized and characterized. A BT unit was incorporated at the junction between blocks (BP 1) in the polytriarylamine block (BP 2) or in the polyfluorene block ( BP 3). An electroluminescent device based on BP 1 exhibited the best performance. This result is reasonably explained by considering the difference in recombination probability in the phase-separated active layers. Different chemical structures of emitting sites afford different emission wavelengths, which are dependent on the electron-donating nature of substituents on the BT rings.
