New photoresponsive polymers and peptides have been developed by incorporation of an azobenzene chromophore. The photochemistry of azobenzene-containing polymers has been reviewed,and the ion-conducting polymer composite film of poly(vinyl chloride)/the azobenzene liquid crystal (4)/lithium perchlorate is a promising material for use in photoinduced image storage.Photoisomerization has also been demonstrated... [Pg.331]

For comparison, a statistical copolymer was synthesized by a common free radical polymerization of hydroxyethyl methacrylate (HEMA) and styrene with AIBN as initiator, followed by a polymeranalogous reaction to the azobenzene-containing polymer (Afn 33,000g mol, PDI 1.6). The copolymer, comprising 28wt% of azobenzene side-groups, exhibits a Tg at 88°C, but no liquid crystalline behavior was observed. [Pg.69]

It is known that a free surface is required for SRG formation. An azobenzene-containing polymer surface covered with a 25 nm-thick non-photoactive layer seems to be sufficient to fully suppress SRG formation [96], Here, we demonstrate that polymers with azobenzene moieties as side-groups and terminal perfluoroalkyl chains can efficiently suppress SRG formation in a similar manner. [Pg.81]
