Scholarcy highlights

  • In this study, we synthesised two series of cholesteric liquid crystal polymers CPQ and CPZ series
  • With the polymethylsiloxanes as the main chain, CPQ series were synthesised by copolymerisation among the monomers ML1, ML2 and ML3 and CPZ series were synthesised by esterification between the CPQ series and the monomer ML4. 1HNMR and FT-IR spectra confirmed the chemical structures of all the monomers and polymers
  • The mesomorphic behaviours and thermal properties were investigated by TGA, DSC, POM and XRD
  • UV–Vis spectra investigated the photoresponse behaviours of CPZ series thoroughly
