The introduction of a metal acetylide fragment in the same conjugated chain as the azobenzene induces the trans-cis-trans isomerization of the azo unit, while the rate of the thermal cis → trans back isomerization increases with increasing overall electron richness of these compounds. These azobenzene-containing ruthenium(II) acetylides show satisfactory processability and give rise to spin-coated uniform thin films. Formation of surface-relief gratings on their amorphous thin films and in a PMMA polymer matrix using a picosecond pulsed laser at 532 nm results in instantaneous inscription: saturation of the first order diffraction efficiency and of the modulation amplitude of gratings were obtained in less than 1 s, while the orientation of these azodyes remains unchanged for up to 6 months.</dcterms:abstract> <dc:creator>Kutta, Roger-Jan</dc:creator> <dcterms:title>Design and photoinduced surface relief grating formation of photoresponsive azobenzene based molecular materials with ruthenium acetylides</dcterms:title> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-06-17T07:17:23Z</dc:date> <dc:creator>Dick, Bernhard</dc:creator> <dc:contributor>Gatri, Rafik</dc:contributor> <dc:contributor>Luc, Jérôme</dc:contributor> <dc:creator>Winter, Rainer</dc:creator> <dc:creator>Fillaut, Jean-Luc</dc:creator> <dc:contributor>Gherab, Kichou N.</dc:contributor> <dc:creator>Gatri, Rafik</dc:creator> <dcterms:bibliographicCitation>First publ. in: Journal of Materials Chemistry 20 (2010), 14, pp. 2858-2864</dcterms:bibliographicCitation> <dc:contributor>Hank, Zakia</dc:contributor> <dc:creator>Gherab, Kichou N.</dc:creator> <dc:contributor>Sahraoui, Bouchta</dc:contributor> <dc:creator>Sahraoui, Bouchta</dc:creator> <dc:rights>deposit-license</dc:rights> <dc:creator>Hank, Zakia</dc:creator> <dc:contributor>Dick, Bernhard</dc:contributor> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103605204-4002607-1"/> <dc:language>eng</dc:language> <dc:creator>Luc, Jérôme</dc:creator> <dcterms:issued>2010</dcterms:issued> <dc:contributor>Winter, Rainer</dc:contributor> </rdf:Description> </rdf:RDF>
