World’s Frst Rapid Circular Polarisation Luminescence Spectrometer

Lewis MacKenzie and Rob Pal have published a review article in Nature Reviews Chemistry, setting out how brightly emitting chiral lanthanide complexes can be used to encode a hidden chiral fingerprint into advanced security inks.

This builds upon recent breakthrough work within the Pal group at Durham (Nature Communications, 2020), which has resulted in the world’s first rapid circular polarisation luminescence (CPL) spectrometer. This review takes recent breakthroughs in both chemistry and instrumentation and combines them to give a perspective on how the field can make ultra-secure chiral security inks a reality.
