Energy Resonance Crossing Controls the Photoluminescence of Europium Antenna Probes

Angew Chem Int Ed Engl. 2017 Jun 26;56(27):7986-7990. doi: 10.1002/anie.201701575. Epub 2017 Apr 4.

Abstract

The energy transfer pathways in lanthanide antenna probes cannot be comprehensively rationalized by the currently available models, and their elucidation remains to be a challenging task. On the basis of quantum-chemical ab initio calculations of representative europium antenna complexes, an innovative energy resonance model is proposed, which is controlled by an overall nonet-quintet intersystem crossing on the basis of spin-orbit coupling among the sublevels of the involved states.

Keywords: ab initio calculations; antenna probes; energy transfer; luminescence; resonant crossing.
