A photoluminescent chiral lead-free hybrid ferroelastic semiconductor with switchable second-harmonic generation

Abstract

[R-3-hydroxylpiperidinium]2SbCl5 is a photoluminescent chiral lead-free organic–inorganic ferroelastic semiconductor showing switchable second-harmonic generation response and clear ferroelastic domains.

Multiple Stimuli‐Responsive Luminescent Chiral Hybrid Antimony Chlorides for Anti‐Counterfeiting and Encryption Applications

“…Recently, Liao et al. also obtained the similar chiral hybrid antimony halide by slow evaporation of a hydrochloric acid solution containing R ‐3‐hydroxypiperidine and antimony chloride [12] . 1 and 2 exhibit special spatial arrangements in the crystal lattices along the a, b, and c axes (Figure S1).…”

Multiple Stimuli‐Responsive Luminescent Chiral Hybrid Antimony Chlorides for Anti‐Counterfeiting and Encryption Applications

“…Recently, Liao et al also obtained the similar chiral hybrid antimony halide by slow evaporation of a hydrochloric acid solution containing R-3-hydroxypiperidine and antimony chloride. [12] 1 and 2 exhibit special spatial arrangements in the crystal lattices along the a, b, and c axes (Figure S1). Both of the enantiomorphic compounds adopt zero-dimensional structure with each discrete [SbCl 5 ] 2À anion interacting with neighboring R-/S-3-hydroxypiperidine cations via inter-molecular hydrogen bonding (Figure S2).…”

A three-dimensional Mn(ii) coordination polymer with ferroelasticity obtained by introducing coligands to form novel networks

“…[2][3][4][5][6][7][8] The study of ferroelastic materials has been of interest for decades because of their superior mechanical properties and their wide range of promising applications in superconductivity, superelasticity, non-linear optics, mechanical switching, and shape memory, and they also play an important role in the design of multiferroic devices. [9][10][11][12] After the discovery of Pb 3 (PO 4 ) 2 with full elastic hysteresis loops in 1976, numerous inorganic ferroelastic materials have been developed over the years, such as BaTiO 3 , BiFeO 3 , Bi 2 O 3 , BiVO 4 , VO 2 and others. [13][14][15] However, inorganic ferroelastics are unable to meet the urgent global demand for environmentally friendly and energy-efficient products due to their high cost and energy consumption.…”
