Delayed Fluorescence and Room Temperature Phosphorescence from a Liquid Arene.

Delayed emission (DF) of fluorescence is generally observed either in solution or in the crystalline state. In the latter, well-defined intermolecular interactions may play a significant role in defining the emission characteristics. Here, we present a trialkoxy-homotruxene that is liquid at room temperature and compare its emission behavior with that of a crystalline analog containing the same π-electron system.
