摘要：

A new levorotatory compound ((S)-9,9'-(6-(1-phenylethoxy)-1,3,5-triazine-2,4-diyl)bis(9H-carbazole)) and its corresponding racemic compound show different intermolecular interactions to restrain nonradiative transition, resulting in an enhanced ultralong organic phosphorescence lifetime from 229.0 ms to 419.8 ms. This work will provide a new insight into the chirality of organic molecules to adjust the ultralong phosphorescence.
