Self-assembly of zinc 3-hydroxymethyl chlorophyll derivatives esterified with different linear alcohols in deep eutectic solvents

Abstract Self-aggregation of Zn 3-hydroxymethyl chlorophyll (Chl) derivatives esterified with different linear alcohols at the 17-propionate residue was investigated in choline chloride-based deep eutectic solvents (DESs). The derivatives esterified with longer alcohols were self-assembled like bacteriochlorophylls in chlorosomes of green photosynthetic bacteria. The physicochemical properties of DESs affected the self-aggregation behaviors of Zn 3-hydroxymethyl Chl derivatives.
