Liu, Jui-Hsiang published the artcilePreparation and characterization of chiral polyacrylates end-capped with bornyl groups in the side chains, Category: esters-buliding-blocks, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (2004), 42(5), 1075-1092, database is CAplus.
Chiral polyacrylates with bornyl end-capped side chains with four kinds of mesogenic moieties (azobenzene, biphenyl, benzoyloxy biphenyl, and Ph benzoate) were prepared The phase properties of the polymers were investigated with X-ray diffraction, differential scanning calorimetry, and polarizing optical microscopy. The thermogravimetric characteristics, the glass-transition temperatures and weight-average mol. weights, of the homopolymers were evaluated. The optical properties of the synthesized polymers in diluted solutions and in the thin-film state were also evaluated. The optical behavior of the composite films upon photoirradiation was investigated through the change in the transmittance of the probe light triggered by UV (365-nm) irradiation UV irradiation and heat treatment caused a reversible intensity change of the probe light at λ = 400 nm. The shrinkage of the photoisomerization of the composite films was also investigated with at. force microscopy. A spot contraction appeared on the surface when it was irradiated with a laser light spot. The contraction was recovered by heat treatment at 80° for 10 min.
