I spent my lockdown workdays writing this review, which I’m very happy to say has been published in Nature Reviews Chemistry. The review takes a look at the new developments in rapid circularly polarised luminescence (CPL) spectroscopy and pairs it with a systematic review and meta-analysis of bright and strongly emitting CPL-active molecules. Complimentary break-through in both molecular design and instrument development mean that rapid-authentication of CPL-active security inks is viable for security applications, e.g. incorporation into ultra-secure documents and currency.
The review also includes a supplementary database of strongly CPL-emitting (gem/glum > 0.05) Europium, Terbium, Ytterbium, Dysprosium, Samarium, and Chromium (molecular ruby) complexes. I hope this database will be particularly useful for those new to the field and conducting their own reviews.
Despite the excellent breakthroughs of the past five or so years, there are still challenges for the field to address, such as temperature-stability of enantiomeric systems through high-temperature lamination and standardised reporting of circularly polarised brightness (CPB) for inter-study comparability of CPL-active molecules.
Thanks to the team at Nature Reviews Chemistry for the excellent editorial process too!
