M. Inoue et al., Effect of photopolymerization on photoconductive behavior in triphenylene discotic liquid crystals, MOLEC CRYST, 365, 2001, pp. 1395-1402
Photoconductivity of the polymerized triphenylene film and monomer liquid c
rystal were evaluated for the nematic order. For the polymerized triphenyle
ne film with a cross-linked network, which was derived from the monomers wi
th six acrylate groups, the observed photocurrent was undetectable (< 10(-1
0)A, 50kV(.)cm(-1)) though the monomer film before polymerization showed it
in the detectable level. On the other hand, the photocurrent of the polyme
r film from the monomer with two acrylate groups was sufficiently detectabl
e (> 10(-9)A, 30kV(.)cm(-1)). Furthermore, the temperature range where the
photocurrent is obtained was extended tip to 200 degreesC for the polymer f
ilm.
