Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Dichromate capture</bold>: A 3D cationic metal–organic framework consisting of distorted octahedral and tetrahedral cages was constructed by using Ag^I and 4, 4′‐bis(1, 2, 4‐triazole). The complex exhibits fast exchange, high trapping capacity, and good selectivity for Cr₂O₇²⁻ through single‐crystal to single‐crystal transformation. The complex also features a bluish violet luminescence that is distinctly quenched after Cr₂O₇²⁻ exchange.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4t3jdqq4" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
