NIR‐Circularly Polarized Luminescence from Chiral Complexes of Lanthanides and d‐Metals.

In recent years, circularly polarized luminescence (CPL) has witnessed a renaissance, due to the increased popularity of CPL as a spectroscopic technique and greater accessibility to instrumentation. New efficient CPL emitters have been designed and many applications, ranging from electronic devices to microscopy have been proposed. Most examples of CPL are within the visible range, while few cases of near infrared (NIR) CPL active complexes are available. NIR‐CPL compounds may have applications in the telecommunication industry, electronic devices and bioassays. In the following, we shall give an overview of the recent developments allowing for the measurements of NIR‐CPL, and describe the chiroptical properties of metal complexes which achieve this feat.
