Two new boronic ester conjugated benzophenone derivatives are reported, which exhibit visible afterglow phosphorescence under ambient conditions and solution-processable thin films. The carbonyl group and pinacol moiety in the molecular design play a crucial role to achieve good phosphorescence efficiency in air.
