Special Issue Information

Dear Colleagues,

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.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

On Prediction of a Novel Chiral Material Y2H3O(OH): A Hydroxyhydride Holding Hydridic and Protonic Hydrogens

Examination of possible pathways of how oxygen atoms can be added to a yttrium oxyhydride system allowed us to predict new derivatives such as hydroxyhydrides possessing the composition M2H3O(OH) (M = Y, Sc, La, and Gd) in which three different anions (H-, O2−, and OH-) share the common chemical space. The crystal data of the solid hydroxyhydrides obtained on the base of DFT modeling correspond to the tetragonal structure that is characterized by the chiral space group P 4 1 . The analysis of bonding situation in M2H3O(OH) showed that the microscopic mechanism governing chemical transformations is caused by the displacements of protons which are induced by interaction with oxygen atoms incorporated into the crystal lattice of the bulk oxyhydride. The oxygen-mediated transformation causes a change in the charge state of some adjacent hydridic sites, thus forming protonic sites associated with hydroxyl groups. The predicted materials demonstrate a specific charge ordering that is associated with the chiral structural organization of the metal cations and the anions because their lattice positions form helical curves spreading along the tetragonal axis. Moreover, the effect of spatial twisting of the H- and H+ sites provides additional linking via strong dihydrogen bonds. The structure–property relationships have been investigated in terms of structural, mechanical, electron, and optical features. It was shown that good polar properties of the materials make them possible prototypes for the design of nonlinear optical systems. Full article

1. Title: Interaction of individual enantiomers and racemic mixtures of chiral [5]-Aza-[5]-helicene and of N-methyl-[5]-Aza-[5]-helicene with a DNA double helix: a molecular dynamics study
Authors: Giuseppina Raffaini, Fabio Ganazzoli, Tullio Caronna
Abstract: [5]helicenes and Aza-[5]helicenes are chiral molecules because of their helicoidal shape, in spite of their lack of asymmetric carbon atoms. Since Aza-[5]helicenes, and in particular N-methyl-5-Aza-[5]helicene may form complex with an anti-cancer drug such as cis-platinum, as reported in previous work, and then can potentially act as an anti-tumoral drug carrier, in this paper we report the results of a molecular dynamics study about the interaction of these molecules with a DNA double helix strand. We first considered the interaction of single enantiomers of both these [5]-Aza-[5]helicenes with DNA to find the preferred interaction sites, in particular at the major or minor groove of the double helix. Afterwards, we investigated the interaction of the same molecules at two different finite concentrations, when the interaction with DNA can be competitive with intermolecular aggregation, modeling systems comprising either pure enantiomers or their racemic mixtures to understand possible differences in the interaction pattern.
