Proof of chirality of J-aggregates spontaneously and enantioselectively generated from achiral dyes

Article Abstract:

Circular dichroism (CD) of J-aggregates is caused by spontaneously and enantioselectively generated chirality of the J-aggregates, and in addition to this a great portion of dichroism of ordered aggregates is found to contribute to the CD signal. It is concluded that the self-reproducing systems in nature is the first example of breaking symmetry in the formation of chiral matter in the liquid state.

Chiral symmetry breaking in interfacial fluids of achiral molecules

Article Abstract:

Chiral symmetry breaking in a fluid of achiral molecules at a liquid- solid interface is studied using atomistic molecular dynamics simulation. Examination of a variety of fluid structural parameters led to the conclusion that chiral symmetry breaking occurs as a result of layer confinement and is largely independent from other aspects of molecular order.
