title: A smart cyclic azobenzene as pendant groups on polymer chains: topological effect of the cyclization on thermal and photoresponsive properties of the azobenzene and the polymer.
abstract: Put a ring on it: A cyclic azobenzene has a much higher melting point, stronger fluorescence, and better film-forming and SRG-formation ability than its linear precursor. Pcyclic-AzoMMA, with cyclic azobenzene pendant groups, has a much higher Tg value (100 °C) than Plinear-AzoMMA, with linear pendants groups (58 °C), and the modulation depth of the photoinduced SRG of Pcyclic-AzoMMA is thirty times larger than that of Plinear-AzoMMA.
