Abnormal room temperature phosphorescence of purely organic boron-containing compounds: the relationship between the emissive behaviorand the molecular packing, and the potential related applications.

ABSTRACT: Purely organic materials with the characteristic of room-temperature phosphorescence (RTP) under ambient conditions demonstrate potential benefits in advanced optoelectronic applications. Exploration of versatile and efficient RTP compounds with low prices is full of challenges due to the slow intersystem crossing process and ultrafast deactivation of the active excited states of organic compounds. Here, a series of boron-containing phosphors were found to present RTP with long-lived lifetimes. Among these commercially available and cheap compounds, (4-methoxyphenyl)boronic acid (PBA-MeO) exhibits long-lived RTP, with a lifetime of 2.24 s, which is among the longest lifetimes of single-component small molecules. Our extensive experiments illustrate that both a rigid conformation and expand
