Photoorientation of azobenzene moieties in self-assembled polyelectrolyte multilayers

Photosensitive Layer-by-Layer Assemblies Containing Azobenzene Groups: Synthesis and Biomedical Applications

“…Polymers with main-chain azobenzene groups are also available for the construction of LbL films (Polymer 8 ) [ 61 , 62 , 63 , 64 ]. These polymers are characterized by flexible alkylene chains linked with rigid azobenzene moieties.…”

Azobenzene Polymers for Photonic Applications

“…Many research groups have investigated the possibility of incorporating optically responsive azobenzene chromophores into the versatile PEM structures (examples presented in Fig. 1.8), including Advincula (Advincula et al, 2001(Advincula et al, , 2003Advincula, 2002;Ishikawa et al, 2002), Kumar and Tripathy (Lee et al, 2000;Balasubramanian et al, 1998), Tieke (Ziegler et al, 2002;Toutianoush et al, 1999;Toutianoush and Tieke, 1998;;Saremi and Tieke, 1998) Heflin (Van Cott et al, 2002), and Barrett . In some cases, copolymers are synthesized, where some of the repeat units are charged groups and some are azo chromophores (Suzuki et al, 2003;Wu et al, 2001a).…”

Photoresponsive behavior of hydrophilic/hydrophobic-based novel azobenzene mesogens: synthesis, characterization and their application in optical storage devices

“…The azobenzene chromophore is a good candidate for storing data optically due to its photosensitivity and good photoisomerization properties. [8][9][10][11] Upon UV illumination ($365 nm related to the p-p* transition), its thermodynamically more stable rod-like molecular form of E or trans isomer is converted into the bent Z or cis isomer. Reverse cis-trans isomerization can be achieved via illumination under visible light ($400-500 nm, related to the n-p* transition).…”
