Abstract Singlet oxygen (1O2) is ubiquitously involved in various photocatalytic oxidation
reactions; however, efficient and selective production of 1O2 is still challenging. Herein, we …

Organic light emitting diodes (OLEDs) employing organic thin‐film based emitters have
attracted tremendous attention due to their widespread applications in lighting and as …

Photochemical stability is one of the most important parameters that determine the
usefulness of organic dyes in different applications. This Review addresses key factors that …

Afterglow optical agents, which emit light long after cessation of excitation, hold promise for
ultrasensitive in vivo imaging because they eliminate tissue autofluorescence. However …

Molecular oxygen, O2, has long provided a cornerstone for studies in chemistry, physics,
