Cr(III) complexes with enhanced metal–ligand covalency enable tunable NIR luminescence and endergonic red-light photoreduction. @GiacomoMorsell2 and team find signs of doublet–doublet annihilation, or excited-state disproportionation. Now in @J_A_C_S: pubs.acs.org/doi/10.1021/jac…

Thrilled to share our new JACS paper on anti-Kasha photoreactivity! We show that higher-lying excited states can drive electron transfer — opening new doors for photoredox catalysis. Huge thanks to @WengerOliver for the incredible mentorship! pubs.acs.org/doi/10.1021/jac…

We show how photoredox catalysis can bypass Kasha’s rule, enabling reactions from higher excited states. This work, led by the exceptional @BjornPfund, offers new insights into photochemical reactivity. Published in @J_A_C_S: bit.ly/3IysmjX
