Yet, they remain barely applied in advanced optoelectronics, such as solid\u2010state lighting and anti\u2010counterfeiting, because of a lack of mechanistic studies. Herein, we describe a class of terminal bis\u2010formamide compounds, H(O\u2550)CNH\u2500(CH\n                    <jats:sub>2<\/jats:sub>\n                    )\n                    <jats:sub>n\u2013<\/jats:sub>\n                    HNC(\u2550O)H, that feature a long afterglow with an average excited\u2010state lifetime (&lt;\u03c4&gt;) close to the second. As an interesting archetype, N,N'\u2010(hexane\u20101,6\u2010diyl) bis\u2010formamide (\n                    <jats:italic>n<\/jats:italic>\n                    \u00a0=\u00a06,\n                    <jats:bold>BFAC6<\/jats:bold>\n                    ) exhibits a &lt;\u03c4&gt; of 0.40 s associated with a photoluminescence quantum yield of 13% in both crystalline solid state and polyvinyl alcohol films (\n                    <jats:bold>BFAC6@PVA<\/jats:bold>\n                    ). Thorough investigations such as temperature\u2010dependent x\u2010ray analyses, time\u2010resolved electronic spectroscopy, and electrochemical impedance spectroscopy suggest that the unusual long\u2010lived emission could be attributed to rigid packing ruled by H\u2010bonding, resulting in an emitting excited state attributed to\u2014 at least\u2014 a H\u2010trapped emissive state. Moreover, the so\u2010called clustering\u2010triggered emission, or clusteroluminescence, is also to be considered here. As a proof of concept, these materials were used for decoration, anti\u2010counterfeiting, and color down\u2010conversion for white hybrid light\u2010emitting diodes, featuring promising performances in terms of device stability, as well as recovery of the initial emission features upon heating\u2013cooling processes.\n
