Generalizing the effects of chirality on block copolymer assembly
Abstract
Chirality is a measure of asymmetry that is important in many branches of science. Homochiral evolution at different length scales is critical for molecular processes in nature (such as communication, replication, and enzyme catalysis) that rely on a delicate balance between molecular and conformational chirality and, most importantly, control the nature of the self-assembly of superstructures of constituent molecules. Here, we compare the homochiral evolution from molecular, to intrachain, to interchain, and, ultimately, to mesodomain chirality from the self-assembly of a pair of block copolymers possessing a chiral block that exhibits one of the two different stereochemistries. The comparison sheds light on the physical mechanisms that link chiral structure across these length scales in this prototypical class of self-assembling materials.
