Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 136725-55-8, is researched, Molecular C4H9ClFN, about Enantiomorphic Perovskite Ferroelectrics with Circularly Polarized Luminescence, the main research direction is enantiomorphic perovskite ferroelec circularly polarized luminescence.COA of Formula: C4H9ClFN.
Materials with circularly polarized luminescence (CPL) activity have immense potential applications in mol. switches, optical sensors, information storage, asym. photosynthesis, 3D optical displays, biol. probe, and spintronic devices. However, the achiral architectures of most of the luminophores severely limit their practical needs. Within this context, mol. ferroelecs. with striking chem. variability and structure-property flexibility bring light to the assembly of CPL-active ferroelec. materials. Herein, we report organic-inorganic perovskite enantiomorphic ferroelecs., (R)- and (S)-3-(fluoropyrrolidinium)MnBr3, undergoing a 222F2-type ferroelec. phase transition at 273 K. Their mirror relationships are verified by both single-crystal X-ray diffraction and vibrational CD (VCD). Furthermore, the corresponding Cotton effect for two chiral crystals was captured by mirror CPL activity. This may be assigned to the inducing interaction between the achiral luminescent perovskite framework and chiral organic components. As far as we know, this is the first mol. ferroelec. with CPL activity. Accordingly, this will inspire intriguing research in mol. ferroelecs. with CPL activity and holds great potential for the development of new optoelectronic devices.
