biostudies-literatureUnknown14(8)Chen JSupramolecular chirality is essential for the development of functional materials. In this study, we report the synthesis of twisted nanobelts based on charge-transfer (CT) complexes using self-assembly cocrystallization starting from asymmetric components. An asymmetric donor, DBCz, and a typical acceptor, tetracyanoquinodimethane, were used to construct a chiral crystal architecture. An asymmetric alignment of the donor molecules induced polar ±(102) facets that, accompanied with free-standing growth, resulted in a twisting along the <i>b</i>-axis due to the electrostatic repulsive interactions. Meanwhile, the alternately oriented ±(001) side-facets were responsible for the propensity of the helixes to be right-handed. Addition of a dopant significantly enhanced the twisting probability Chemical science2091-2096https://www.ebi.ac.uk/biostudies/studies/S-EPMC9945330biostudies-literaturePolarization-induced nanohelixes of organic cocrystals from asymmetric components with dopant-induced chirality inversion.PMC9945330Liu ZMa SChen JZhang JXiang WYang CfalsePolarization-induced nanohelixes of organic cocrystals from asymmetric components with dopant-induced chirality inversion.Supramolecular chirality is essential for the development of functional materials.
