英文摘要： Based on the molecular design strategies, we plan to synthesize polyelectrolytes and PPV derivative materials including phenoxy (or oxyethyl) sulfosalt group side chain structure. We will study on the ground and excited state structure of the polyelectrolytes containing different group (phenoxy or oxyethyl sulfosalt) and PPV derivative with oxyethyl in the main chain using the quantum theory methods, calculate their affinity energies, ionization energy and electron emission information, and illustrate the relationship between the structures of the polyelectrolytes and PPV derivative with phenoxy sulfosalt (or oxyethyl) group and the electron transport and photoelectric properties in theory. We will systematically investigate the strucutre, stability, solubility, compatibility and electroluminescence device properties etc of the polyelectrolytes and PPV derivative materials via modern analysis and measurement methods, and explore the fabrication of the PLEDs device with low cut-in voltage, high luminance and current efficiency.
