Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Three new organically templated copper(I) halides formulated (C<sub>10</sub>H<sub>22</sub>N<sub>2</sub>)<sub>2</sub>[Cu<sub>4</sub>I<sub>8</sub>] (<bold>1</bold>), (C<sub>10</sub>H<sub>22</sub>N<sub>2</sub>)<sub>2</sub>[Cu<sub>4</sub>I<sub>4</sub>Br<sub>4</sub>] (<bold>2</bold>), and C<sub>20</sub>H<sub>44</sub>N<sub>4</sub>[Cu<sub>4</sub>I<sub>4</sub>Br<sub>4</sub>] (<bold>3</bold>) {C<sub>10</sub>H<sub>22</sub>N<sub>2</sub> = <italic>N</italic>, <italic>N</italic>′‐diethyl‐1, 4‐diazabicyclo‐[2.2.2]octane (<bold>T1</bold>), C<sub>20</sub>H<sub>44</sub>N<sub>4</sub> = 4, 4′‐(butane‐1, 4‐diyl)bis(1‐ethyl‐1, 4‐diazonia‐bicyclo[2.2.2]octane) (<bold>T2</bold>)} were synthesized under solvothermal conditions by an <italic>in situ</italic> copper reduction route. The structures of these compounds are constructed by similar inorganic anion cluster skeleton, formulated Cu<sub>4</sub><italic>X</italic><sub>4</sub><italic>X</italic>′<sub>4</sub> (<italic>X</italic> = I, <italic>X</italic>′ = I, Br), and organic templates. The organic templates <bold>T1</bold> and <bold>T2</bold> in the structures originated from the <italic>in situ</italic> N‐alkylation reaction between DABCO (DABCO = <italic>N, N</italic>′‐dimethyl‐1, 4‐diazabicyclo[2.2.2]octane), alcohol solution, and alkyl bromine. Compounds <bold>1</bold>–<bold>3</bold> were characterized by X‐ray crystal structure, elemental analysis, TG, IR, XRD, and XPS. These compounds exhibit strong pale green, orange, and light orange luminescence at ambient temperature, respectively, and the luminescent properties of them in the solid state were also investigated.</p> </abstract>
