Synthesis, structure, crystal growth and characterization of a novel semiorganic nonlinear optical l-proline lithium bromide monohydrate single crystal

Ionic Co‐Crystal Formation as a Path Towards Chiral Resolution in the Solid State

“…Grinding dl ‐proline with LiCl and LiBr yields a solid product for which an XRPD pattern was measured and found comparable to those of the previously reported enantiopure, isomorphous, co‐crystals with LiCl ( l ‐Pro ⋅ LiCl ⋅ H 2 O, YOXBET) and LiBr ( l ‐Pro ⋅ LiBr ⋅ H 2 O NOCXIO), respectively, indicating the formation of a conglomerate (see Scheme ).…”

“…Reaction in solution of l ‐proline with LiCl and LiBr, both in 1:1 and 2:1 stoichiometric ratio (see Scheme ), resulted in the formation of the known ICCs l ‐Pro ⋅ LiCl ⋅ H 2 O (YOXBET), l ‐Pro ⋅ LiBr ⋅ H 2 O (NOCXIO), (LiBr, 1:1), EVUVUN (LiCl, 2:1) and EVUVIB (LiBr, 2:1) …”

“…[23] As ar esult, hydrated ionic co-crystals between l-proline and LiCl, LiBr, SrCl 2 ,C aCl 2 (1:1 stoichiometry amino acid:salt) have been synthesized in solution, characterized and investigated as second order non-linear optical materials. [23,24] Anhydrousi onic co-crystals between l-proline and LiCl, LiBr,C aCl 2 (stoichiometry 2:1 amino acid:salt) have also been reporteda sm etal-organic materials. [25] Coordinationo fr acemic proline to am etal centre has not been extensively investigated, and only two solids containing ZnCl 2 and CaCl 2 are known (LUPTEV [25f] and WOCPUB, [26] respectively).…”

Nucleation kinetics and dielectric characterization of L-Proline Potassium Chloride (LPPC) single crystals

“…The calculated critical radius r* decreases with the increase of supersaturation and consequently the nucleation rate (J) increases with increase of supersaturation. The nucleation rate is observed to be increasing with thesupersaturation ratio and if the nucleation rate is low, the formation of multi-nuclei in the solution will be less and hence big-sized crystals could be grown [8][9][10][11][12][13][14][15]. …”

Structural, Vibrational and Thermal Properties of Semi Organic Nonlinear Optical Glutamic Added Lithium Sulphate Monohydrate Crystal

“…Owing to the increasing need of new materials with high NLO efficiency and improved physical properties, new approach has been developed to hybrid organic-inorganic materials with their advantages for technological applications [1]. The materials that have a potential to tailor high optical nonlinearity of an organic ion with favorable mechanical and thermal properties of an inorganic counter ion, turned out to be superior quality semi organic materials [2,3]. Extensive research has revealed that Amino acids serve as attractive organic candidates , as they contain the chiral nature, wide hydrogen bonding network, a proton donor carboxyl (-COOH) group and a proton acceptor amine (-NH2) group with a side chain (R) group specific to each amino acid.…”
