CPL and only CPL!
Just as CD measures differences in absorption of circularly polarized light,
CPL reveals what no other measurement can — the true chiral signature of excited states — unlocking insights invisible to absorption, fluorescence, or CD.
CPL is useful with all emissive chiral sample types including lanthanides, helicenes, polyfluorenes, supramolecular assembles, gold nanoclusters chiral carbon dots, GFP, and so much more.
