Abstract

Chlorinated chlorophylls (chl) came into focus in recent years with reports suggesting the participation of 132-HO-20-Cl-chl a in photosystem I <1,2>. However, studies revealed the artificial formation of this compound <3,4>. Nevertheless chlorinated chlorophylls deserve further attention, since their unique physical and chemical properties make them promising model compounds for comparative chl studies.
