To explore the effect of molecular packing in a liquid-crystalline phase, chiral liquid-crystalline methacrylate monomers with polymerizable group attached to the rigid core through a short methylene spacer (carbon number of 2) and a long methylene spacer (carbon number of 11) were synthesized. The monomers were found to exhibit chiral smectic C and smectic A phases by optical polarizing microscopy and DSC. The monomers were photopolymerized which 1-hydroxycyclohexyl phenyl ketone as a photoinitiator at various temperatures. The polymerization was carried out in a cell which was composed of two glass substrates with ITO electrodes. It w as found that reactivity of the monomer having a short spacer is higher than that of the monomer having a long spacer, Furthermore, the stored image obtained by photopolymerization in SmC* phase has been stable for three months.
