摘要
New thiophene-linked conjugated polynoxaline PTQx and oligoquinoxaline TQx were synthesized and characterized. Comparison of their electronic absorption spectra revealed the dominant role of intramolecular charge transfer in their electronic structures and properties. PTQx exhibited a reversible electrochemical reduction and high electron affinity and ionization potential that make it an attractive n-type conjugated polymer. Evaluation of PTQx as an electron transport material for PPV-based light-emitting devices showed that it was far superior to previous electron transport materials.
