Anisotropic porous liquid crystal (LC) particles with ∼60 μm diameters were prepared using microfluidics and directional UV photopolymerization of 1,4-bis[4-(6-acryloyloxyhexyloxy)benzoyloxy]-2-methylbenzene/4-cyano-4′-pentylbiphenyl (RM257/5CB) mixtures at room temperature in the presence of a magnetic field.
