Growth and characterization of a new semiorganic nonlinear optical crystal-Bis (thiourea) lithium chloride

The complexing ability of n-substituted thiourea derivatives as chelating ligands in the reaction with PdCl2

“…The highest index ІС 50 (1.5•10 -4 M) was determined for the palladium complex with HL 3 (5). Both compounds studied had the proapoptotic effect, but in contrast to the highest ІС 50 index, cytostatic and proapoptotic effects for complex compound 5 were more pronounced.…”

“…The comparison of the 1H NMR spectra of thioureas HL 3 , HL 4 and complexes 5,6 shows that the proton signals of NH (the thioureate group) and =C2Hallyl by ∆δ=+1.289/+1.648, +0.301/+0.332 ppm undergo the most significant downfield shifts while the multiplet of the allyl fragment =С1Н2 is significant upfield by -0.544/-0.824 ppm. The most characteristic for the 1H NMR spectra of these complexes is splitting of the C3H2 signal to the two doublets.…”

“…The presence of unshared electron pairs in the sulphur atom and two nitrogen atoms allows to form the complex compounds with transition metal salts of the different type, many of which possess valuable applied properties (optical, semiconductor, biological, etc.) and are employed in various fields of science and technology [4][5][6][7]. Thioureas are of prime importance as anticancer drugs due to their ability to inhibit the enzymes that are involved in the malignant tumour formation processes (tyrosine kinase, protein tyrosine kinase and NADH oxidase) [8][9][10].…”

Synthesis of the semi-organic nonlinear optical crystal l-glutamic acid zinc chloride and investigation of its growth and physiochemical properties

“…This kind of dipolar nature of amino acids proves to be an ideal candidate for NLO applications. The literature reveals that complexes of amino acids with inorganic (metal) salts are promising NLO materials for optical applications, such as optical communication, optical computing, optical information processing, optical disk data storage, laser fusion reactions and laser remote sensing [25][26][27]. Additionally, considerable effort is being made to find new materials that have the optimal characteristics needed for use as nonlinear optical elements [28][29][30][31][32].…”
