Such materials may be employed in security elements, 3D display technologies, and optical data storage devices which, due to their chirality, can operate via two distinct channels. In addition, hybrid perovskites are known to act as efficient absorbers of radiofrequency radiation. The structural variability of perovskites represents one of the key factors responsible for their unique physicochemical properties. The central concept of the project is to establish fundamental principles for the synthesis of chiral hybrid perovskites with tailored optical characteristics. Incorporation of a chiral cation is expected to yield materials that simultaneously exhibit parity-breaking effects associated with chirality and the semiconducting properties typically inherent to hybrid perovskites. According to the working hypothesis, the selective introduction of cations bearing specific functional groups—which in turn govern crystal packing motifs—constitutes a modern and promising strategy for the development of hybrid perovskites, enabling the creation of advanced functional materials with programmable properties. The objective of the project is the synthesis of chiral organic–inorganic hybrid perovskites containing divalent metal cations (Pb²⁺, Sn²⁺, Ge²⁺) and trivalent metal cations (Bi³⁺, Sb³⁺), combined with chiral amino acid cations (e.g., arginine, asparagine, glutamine, histidine, tryptophan, tyrosine, etc.), and featuring predefined crystal framework types that ensure the semiconducting behavior characteristic of hybrid perovskite materials.
