Crystal structure and characterization of l-arginine dichloride monohydrate and l-arginine dibromide monohydrate

Synthesis, Crystal Growth, Spectroscopic and Electrical Properties of 5-tert-Butyl-1,2,3-trinitrobenzene

“…Also, organic crystals of nitrophenol family play a prominent role in nonlinear optical area due to their superior qualities such as high laser damage threshold, wide transparency windows, and extended thermal stability. As a consequence, a large number of nitrophenol families of crystals have been already grown and reported [3][4][5][6][7][8][9][10][11][12][13]. In a particular case, the laser damage thresholds of nonlinear optical crystals of sodium p-nitrophenolate dehydrate are 11.16 ± 0.28 GW cm −2 and 1.25 ± 0.02 GW cm −2 for 1064 nm and 532 nm laser wavelengths, respectively [14,15], while the laser damage threshold of standard potassium dihydrogen phosphate (KDP) is 0.2 GW cm −2 [16].…”

Synthesis and structural characterization of Keggin polyoxometalate compounds with argininium(2+) cations

“…It is also the most basic of the natural aminoacids, since it contains a terminal guanidyl group, in addition to the aamino group. It can easily form salts through the reaction with acids, such as phosphoric, hydrofluoric and hydrochloric acids [1], which generally crystallize in non-centrosymmetric space groups, such as P2 1 2 1 2 1 , P2 1 or P1 [1][2][3], due to the presence of the chiral carbon atom. These properties make L-arginine a natural candidate for the development of new materials since chirality plays an ever increasing role in various fields, namely catalysis, where chiral selectivity is a major goal, biomedical applications, where many biological activities involve chiral selectivity, and in materials science, where the development of accentric materials is a requirement for some optical applications.…”

“…The search for new argininium salts led to the preparation and crystal structure determination of many compounds with inorganic anions and either HArg + or H 2 Arg 2+ cations. In particular, the argininediium cation has been found in several crystals formulated (H 2 Arg)X 2 , with X = F À [6], Cl À [3,6], Br À [3,6], NO 3 À [6][7][8][9], IO 3 À [6,10], H 2 AsO 4 À [11] and H 2 PO 4 À [6,12,13] (a few of them hydrated).…”

Studies on the growth and characterization of a NLO active sodium substituted lithium p-nitrophenolate single crystal

“…Over recent years a series of studies have been performed on organic optical materials with high nonlinearity for variety of applications in electrooptic and second harmonic generation (SHG) devices [1][2][3][4]. However, there are some disadvantages in using organic molecular crystals for frequency conversion and optical switching.…”
