|We investigated the photorefractive
performance of the polymer dissolved liquid crystalline composite
(PDLCC), in which liquid crystalline polymer and low-molar-mass liquid
crystal are miscible without phase separation, doped with three kinds
of fullerene derivatives with different length of alkyl groups. The
photorefractive performance was improved for the photorefractive PDLCC
doped with fullerene derivatives with long length of alkyl groups. The
photorefractive grating formation originates in the cooperative
reorientation of the liquid crystalline director and the space charge
field was estimated using the elastic continuum theory and the field
for the PDLCC doped with the functionalized fullerene with longer alkyl
side groups was larger than that for the PDLCC doped with conventional
