Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Put a ring on it</bold>: 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 <italic>T</italic>_g 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.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4t78fxsw" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
