This paper reviews our recent studies on several systems. These include azobenzene-containing thermoplastic elastomers that can be used to prepare mechanically tunable diffraction gratings, side-chain azopyridine polymers for combined self-assembly and photoactivity, azobenzene polymer-stabilized ferroelectric liquid crystals whose bulk alignment can be achieved by light with no need for surface orientation layers, and, finally, self-assembled photoactive liquid-crystal gels that can display light-induced reorganization leading to the formation of electrically switchable diffraction gratings. © 2013 Walter de Gruyter GmbH, Berlin/Boston Pure and Applied Chemistry De Gruyter 76/7-8(2004-01-01), 1499-1508 0033-4545 76:7-8<1499 2004 76 pac https://doi.org/10.1351/pac200476071499 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1351/pac200476071499 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Zhao Yue Département de Chimie, Université de Sherbrooke, Sherbrooke, Québec J1K 2R1, Canada NATIONALLICENCE 773 0- Pure and Applied Chemistry De Gruyter 76/7-8(2004-01-01), 1499-1508 0033-4545 76:7-8<1499 2004 76 pac CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
