The interactions between Λ and Δ enantiomers of ruthenium(II)‐phenanthroline cationic complex ([Ru(phen) 3 ] 2+ ) and three anionic porphyrins have been characterized by absorption, circular dichroism (CD), fluorescence, and resonance light scattering (RLS). The three porphyrins used in this study have been chosen for the different number (two or four) and reciprocal (symmetrical, cis or trans ) disposition of the anionic (4‐sulphonatophenyl) peripheral groups in the meso positions. All the techniques evidence the formation of inorganic–organic hybrids. In particular, CD and fluorescence measurements show that the inorganic moiety is able to transfer to porphyrins not only chirality (as shown from the appearance of an induced CD signal (ICD) in the absorption region of porphyrins) but, most likely, also energy.
