The photocurrent behavior in polydiacetylene (PDA) single crystals of PTS (poly-(2, 4-hexadiyne-1, 6-diol bis(p-toluenesulfonate)) and MADF (poly-(1-(3-(methylamino)phenyl)-4-(3, 5-bis (trifluoromethyl)-phenyl) butadiyne)) have been investigated by using steady state photoconductivity measurements. These measurements were carried out as a function of sample temperature and incident light polarization. PTS and MADF show completely different behavior in these measurements. These differences between PTS and MADF suggest that the side groups of PDA strongly influence the photocurrent behavior in PDA.
