Special Issue "Chiral Materials"
A special issue of Materials (ISSN 1996-1944).
Deadline for manuscript submissions: 30 September 2021.
The interaction of light with chiral structures has recently become an important research topic owing to its fundamental physical importance as well as the high potential for diverse technological implementations. Nanostructured materials—metamaterials and metasurfaces—form promising routes for ultra-compact optical elements, thus providing extended control over new functionalities. Chiral structures are known to induce a different optical response for the illumination of right- and left-handed circular polarization or so called optical activity. While the chiral signature of natural materials is rather weak, the nanostructured materials have the advantage of enhancing the optical activity in several orders of magnitude, providing an intriguing platform for sensing and a novel type of light–matter interaction.
In this Special Issue, the progress of current and novel research avenues in chiral materials and chiral light matter interactions will be discussed.
It is my pleasure to invite you to submit a manuscript to this Special Issue. Full papers, communications, and reviews are all welcome.

Abstract: Helicenes are interesting chiral molecules without asymmetric carbon atoms but with intrinsic chirality. Fuctionalized 5-Azahelicenes can form non-covalent complexes with anticancer drugs and therefore be potential carriers. In this theoretical study based on atomistic molecular dynamics simulations the interaction between (M)- and (P)-5-azahelicenes with double helix B-DNA is investigated. At first the interaction of single pure enantiomer with DNA is studied, in order to find the preferred site of interaction at major or minor groove. Afterwards, the interaction of the enantiomers at different concentrations was investigated considering both competitive adsorption on DNA and possible helicenes self-aggregation. Therefore, racemic mixtures were studied. The paper highlights the different structural selectivity for DNA binding for two enantiopure compounds and the influence of concentration on adsorption and self-aggregation process. The helicenes studied are able to bind DNA modulating or locally modifying its hydrophilic surface into hydrophobic after adsorption of the first helicene layer partially covering the negative charge of DNA at larger concentration. The (P)-enantiomer shows a preferential binding affinity of DNA helical structure during competitive adsorption in the racemic mixtures. These DNA/helicenes non-covalent complexes exhibit a more hydrophobic exposed surface and after self-aggregation a partially hidden DNA chiral architecture to biological environment.
