Chiral Bis-chlorin: enantiomer resolution and absolute configuration determination.
[structure: see text] A racemic mixture of the ethane-bridged bis(zinc octaethylchlorin) was successfully resolved for the first time to yield two enantiomers that exhibit substantial CD signals in the regions of chlorin B and Q transitions. The absolute configuration of the corresponding enantiomers was assigned and the origin of its high optical activity was rationalized through a combined spectral, crystallographic, and theoretical analysis.
