Liquid crystal assisted replica molding method to align uniaxial molecules in patterned polymer at ambient temperature

In this paper, we demonstrate an easy approach - liquid crystal assisted replica molding method - to align uniaxial molecules in a patterned polymer at ambient temperature. During the replica molding process, the orientation of liquid crystals was parallel to the groove of the grating and the uniaxial molecules were aligned by liquid crystals. In order to confirm our observations, we had measured photoluminescence (PL) and polarized absorption spectra to quantify the degree of alignment. This approach to align uniaxial molecules in a polymer at ambient temperature opens up a simple way to manufacture optoelectronic and electronic devices.
