Synthesis, characterization, and air stability study of pyrimido[4,5-g]quinazoline-4,9-dione-based polymers for organic thin film transistors

This study reports the synthesis of two novel π-conjugated pyrimido[4,5-<italic>g</italic>]quinazoline-4,9-dione (PQ) based polymers and reveals that the air stability of PQ based polymers is critically affected by the donor comonomer.
