Here we show that the far-red spin–flip (SF) transitions of a molecular Cr(III) complex give intense MCD (magnetic circular dichroism) and in particular MCPL (gMCPL up to 6.3 × 10−3 T−1) even at magnetic fields as low as 0.4 T. Cr(III) doublet states and SF emission are nowadays the object of many investigations, as they may open the way to several applications. Due to their nature, such transitions can be conveniently addressed by MCPL, which strongly depends on the zero field splitting and Zeeman splitting of the involved states. Despite the complexity of the nature of such states and the related photophysics, the obtained MCPL data can be rationalized consistently with the information recovered with more established techniques, such as HFEPR (high-frequency and -field electron paramagnetic resonance). We anticipate that emissive molecular Cr(III) species may be useful in magneto-optical devices, such as magnetic CP-OLEDs.}, organization = {MUR through PRIN-PNRR project (P20229723Z)}, organization = {Ministerio de Ciencia Innovación y Universidades for a Ramón y Cajal contract (grant RYC2022- 037255-I) funded by MCIN/AEI/10.13039/501100011033 and FSE+}, organization = {Ministerio de Ciencia e Innovación for financial support (project PID2022-138090NB-C21 funded by MCIN/AEI/10.13039/501100011033/FEDER,UE)}, organization = {National High Magnetic Field Laboratory which is funded by the US National Science Foundation (Cooperative Agreement DMR-212856) and the State of Florida}, publisher = {Royal Society of Chemistry}, title = {Magnetic circularly polarized luminescence from spin–flip transitions in a molecular ruby†}, doi = {10.1039/D4SC04718D}, author = {Gabbani, Alessio and Poncet, Maxime and Pescitelli, Gennaro and Carbonaro, Laura and Krzystek, J. and Colacio Rodríguez, Enrique and Piguet, Claude and Pineider, Francesco and Di Bari, Lorenzo and Jiménez Gallego, Juan Ramón and Zinna, Francesco}, }
