Exciplex–Excimer Emission from Organic Molecular Dyads

Summary

In recent years aggregates of molecular dyads that are only stable in the excited state, such as excimers and exciplexes, have become quite useful as molecular probes for the detection of various analytes as well as for the measurement of distances on the nanoscale. Furthermore, the anisotropy of the emitted and absorbed light of such dyads offers another approach to obtain useful information on a molecular scale. In addition, the modulation of the emitted light of these dyads has resulted in a strategy to obtain organic light‐emitting diodes that emit white light. Moreover, the role of excimers and exciplexes in organic solid‐state lasers and organic photovoltaics is still a topic for debate, where they can either be detrimental to the performance of the device or an integral part of it. The following book chapter will give the reader an overview of the various applications for excimers and exciplexes.
