Synthesis, structural, vibrational, thermal, dielectric and optical properties of third order nonlinear optical single crystal for optical power limiting applications

Crystal structure and Hirshfeld surface analysis of 2-aminopyridinium hydrogen phthalate

“…Pyridinium families are now considered to be potential materials for optical applications because of their flexibility in molecular design, strength and thermal stability, which are derived from delocalized clouds of electrons. Another electronic field of research related to 2-aminopyridinium salts is focused on their optical limiting and frequency-conversion applications (Liu et al, 2015;Siva et al, 2019). The present work is a part of a structural study of new proton-transfer compounds of 2-aminopyridine with phthalic acid and the corresponding hydrogen-bonding interactions.…”

Synthesis, crystal structure, potential drug properties for Coronavirus of Co(II) and Zn(II) 2-chlorobenzoate with 3-cyanopyridine complexes

“…Arylcarboxylic acids and N-donor ligands are widely used in the synthesis of supramolecular structures [6] . Supramolecular structures are formed through different components interacting with non-covalent interactions such as hydrogen bonding [7] , [8] , [9] , [10] , dipole-dipole interactions, steric repulsions, van der Waals interactions, and London dispersion forces. These non-covalent interactions are important for biological systems as well as contribute to the stability of the crystal structure [11] , [12] , [13] , [14] , [15] .…”

The Study of Structural, Optical, and Dielectric Properties of Magnesium Chloride-Doped Triglycine Sulphate Ferroelectric Single Crystals

“…Triglycine sulphate (TGS) (NH 2 CH 2 COOH) 3 H 2 SO 4 is one of the most broadly studied ferroelectric materials, which shows ferroelectric transition at ambient temperature (49 °C) [10]. It belongs to the monoclinic crystal system associated with polar space group P2 1 in the ferroelectric phase, and it crystallizes in the P2 1 /m space group in the paraelectric phase [11]. However, pure TGS crystals have some drawbacks over doped TGS crystals such as easy depolarization by thermal and electrical means, ferroelectric properties possessing high mobility, and low Curie temperature [12].…”
