Synthesis and characterization of photosensitive liquid crystalline polybenzylidene esters and ethers containing alkanones and methylene spacers in the main chain

Abstract

Main chain liquid crystalline polymers with photosensitive groups have attained special attention owing to the presence of dual functionalities The mesogenic groups contributes to the LC properties and the photoactive groups in the polymer backbone may facilitate photoisomerization photocrosslinking photodimerization photodissociation and photoassociation of the polymer chains under the influence of UV irradiation newline
