| Recently developed photoconductive polymer systems, polyparacyclophanes doped with low-molecular-weight acceptors, combine high charge carrier mobility provided by extended π-electron systems along cofacially arrayed aromatic rings, with effective photogeneration in visible range due to formation of charge-transfer complexes with the dopants. In a series of polyparacyclophane complexed with different benzoquinones it was found that the photoconductivity gain coefficient in the visible range increases with increasing electron affinity of the dopant and that the gain coefficient is higher for higher dopant concentration. The influence of the charge-transfer complex formation between various polyparacyclophanes and various acceptors on the charge carrier generation both in the dark and under illumination is discussed. |
