Indolizines are a promising class of biologically active compounds. However, photocatalytic methods for their selective derivatization scarce in the literature.

Recent advances with luminescent mononuclear chromium(III) complexes have provided important molecular design guidelines for enhancing their photoluminescence properties. Applying these modern aspects of coordination chemistry to dinuclear Cr III complexes, which are mostly not but show interesting magnetic properties, seems attractive exploring functional compounds exchange interactions and light‐induced activity. In this concept, the key structural requirements ferromagnetic respectively, analyzed. Rational merger magneto‐optical–structural correlations leads new types coupling room temperature luminescence, photophysical properties make them promising photosensitizers energy transfer. These concepts open door novel can allow crosstalk photophysics, photochemistry, interactions.
