Abstract

Light interaction with nematic liquid crystals doped with high-molecular polymer MEH-PPV (poly[2-methoxy-5-(2'-ethylhexyloxy)-l,4-phenylenevinylene]) has been studied. The director reorientation away from the light field was found within the absorption band of the polymer. The reorientation is explained by the appearance of the torque due to changing the intermolecular forces between the polymer macromolecules and nematic-host molecules under polymer excitation by light absorption.
