Towards Understanding Photoswitchable Materials: Molecular Dynamics Simulation Studies of Azobenzene-Containing Polymers — •Marcus Böckmann and Nikos Doltsinis — Institut für Festkörpertheorie, Westfälische Wilhelms-Universität Münster, Münster, Germany
A large number of photoresponsive materials are made from
polymers or liquid crystals that contain azobenzene (AB)
as photochromic unit [1].
In this contribution, we will report on results from our theoretical studies
based on multiscale molecular dynamics (MD) simulation techniques
[2-4] applied to helical foldamers [4], artificial muscles [5],
liquid crystals [3], and
the phenomenon of photofluidity [6] yielding surface relief gratings (SRGs)
in an active layer of poly-disperse-orange-3-metacrylamide (PDO3M).
