Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Selective response:</bold> Two new cation‐responsive two‐photon absorption (2PA) dyes containing phenylaza[18]crown‐6 moieties and 1, 2, 3‐triazole units as π‐linkers are described. One of the dyes (see picture) without cations exhibits a 2PA cross‐section of 190 GM. Through binding of cations, the 2PA cross‐section is reduced or enhanced.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh11p1t834" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
