Shape effect-induced spiral superstructures in a self-assembled achiral disc-bent core amphiphile

Abstract

Herein, we aim to demonstrate the shape effect of a giant molecule on the self-assembly of supramolecules. A bent-core (BC) molecule was covalently linked to a disc-like hexa-peri-hexabenzocoronene (HBC), giving a disc-bent core amphiphile. As a result, the induced hierarchical chirality driven by the shape effect on the forming columnar phase gives a two-dimensional nano-ribbon with spiral texture from double-stranded supracolumns.
