Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201502442-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Persistent room temperature phosphorescence (RTP)</bold> from pure organic luminogens can be rationally realized based on the crystallization‐induced phosphorescence phenomenon and severe crystallization. A perfect crystal with dense molecular packing and effective inter­molecular interactions isolates the triplet excitons from quenching sites and significantly blocks the high‐energy vibrational dissipation, thus yielding long‐lasting RTP. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgkv860gxs" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
