Synthesis of benzo[de]isoquino[1,8-gh]quinolines and light-induced electron transfer in their composites with conductive polymer poly(3-hexylthiophene)

Benzo[de]isoquino[1,8-gh]quinolines were prepared by the reaction between 1,5-diethynyl-9,10-anthraquinones and urea in DMF. Light-induced electron transfer from regioregular poly(3-hexylthiophene) to the synthesized molecules was detected by an EPR spectroscopy technique.
