The range of carriers in thin crystalline films of the conjugated polydiacetylene derivatives 3 and 4BCMU [with the side groups R1=R2=–(CH2)3–OCO–NH–CH2–COOC4H9 and –(CH2)4–OCO–NH–CH2–COOC4H9] are demonstrated to be greater than 110 and 90 μm, respectively, and the quantum efficiencies for carrier generation are determined. The films are created as a result of electron-beam-induced topochemical polymerization of a thin surface layer on a crystalline monomer substrate. The polymer films are subsequently separated from the underlying monomer and deposited onto a series of interdigitated electrodes with varying interelectrode separation. The range and generation efficiencies are deduced by measuring the photocharge induced on the electrode system as a result of a laser pulse. Comparisons are made with bulk single crystals. © 1999 American Institute of Physics.
