Diastereoselective control of bacteriochlorophyll e aggregation. 3'-S-BChI e is essential for the formation of chlorosome-like aggregates
Article Abstract:
Supramolecular bacteriochlorophyll (BChI) e aggregates in four different solvent systems are investigated. Two different aggregate structures of HPLC-purified BChI e species, 3(super 1)-R-8-ethyl-12-ehtyl BChI e, 3(super 1)-R-8- propyl-12 ethyl BChI e, 3(super 1)-S-8-propyl-12-ethyl BChI e, and 3(super 1)-S-8-isobutyl-12-ethyl BChI e, in cyclohexane, n-hexane, H2O/monogalactosyldiglyceride, or H2)/lecithin, are indicated as judged from absorption, circular dichroism, infrared, and resonance Raman spectroscopies.

MAS NMR structures of aggregated cadmium chlorins reveal molecular control of self-assembly of chlorosomal bacteriochlorophylls
Article Abstract:
Magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy is used to investigate the self-organization of bacteriochlorophylls in chlorosomal light-harvesting antennae. The results reveal a balance between relatively strong local interactions and contributions to the free energy of the system associated with a longer length scale.
