摘要

Pyrazino[2,3- g ]quinoxaline-2,7-dione ( PQx ) was used as a building block for π-conjugated polymer semiconductors, which demonstrated a strong acid affinity by showing marked bathochromic shifts in their absorption spectra. These polymers exhibited semiconductor performance in organic thin film transistors (OTFTs). Copolymers of PQx and bithiophene exhibited electron-dominant ambipolar transport characteristics with electron mobilities of up to 4.28 × 10 ~(?3) cm ~(2) V ~(?1) s ~(?1) and hole mobilities of up to 5.22 × 10 ~(?4) cm ~(2) V ~(?1) s ~(?1) , while copolymers of PQx and thieno[3,2- b ]thiophene exhibited hole-dominant ambipolar transport characteristics with hole mobilities of up to 4.82 × 10 ~(?2) cm ~(2) V ~(?1) s ~(?1) and electron mobilities of up to 3.95 × 10 ~(?3) cm ~(2) V ~(?1) s ~(?1) .
