On page 2046, the authors made the following statement: ‘Katz and collaborators have perhaps most elegantly constructed a glycol linked chlorophyllide dimer,5a which self-assembles into a folded conformer by two hydrate bridges via oxygen metal coordination and carbonyl hydrogen bonding.’
The authors would like to further clarify that prior to this chlorophyllide dimer, the covalent linkage self-assembling chlorin dimer concept was originally introduced by S. G. Boxer and G. L. Closs with ethylene glycol linked pyrochlorophyllide a dimer, which is a similar chlorophyll derivate, apart from the fact that the compound lacks 132(R) methoxycarbonyl groups.5b
