Photomigration in azo-polymer thin films probed by atomistic molecular dynamics simulations — •Marcus Böckmann and Nikos Doltsinis — Institut für Festkörpertheorie, Westfälische Wilhems-Universität, Münster, Germany

Photoresponsive polymers containing azobenzene (AB) as the photochromic unit are well known for allowing photopatterning and the fabrication of surface relief gratings (SRGs) [1,2]. In this contribution, we will report on recent results from our theoretical studies based on multiscale molecular dynamics (MD) simulation techniques [3,4] applied to the phenomenon of light-induced mass transport – also being termed photofluidity [5] – in an active layer slab of poly-disperse-orange-3-metacrylamide (PDO3M) [6].
