Theorie der photo-mechanischen Eigenschaften von azobenzolhaltigen Polymeren: licht-induzierte Deformationsdynamik
Zusammenfassung der Projektergebnisse
To conclude, the orientation approach based on the effective potential (1) provides results in a good agreement with experimental data for photodeformation of azobenzene-containing polymers. In this project we justify this approach by explicit theoretical study and computer simulations of photoisomerization kinetics. Thus, the orientation approach receives now a strong physical background from the first theoretical principles, from computer simulations and from experimental data. The effective orientation potential can be applied to study the reorientation kinetics, deformation and mass transport of a wide spectrum of azo-materials including amorphous, liquidcrystalline and cross-linked polymers, azobenzene-functionalized dendrimers and brushes, azobenzene-decorated plasmonic particles and many others. The established structure−property relationships can be used for designing specific photodeformable materials with target technologically important properties.
