Crystal structure and vibrational analysis of novel nonlinear optical L‐histidinium tetrafluoroborate (L‐HFB) single crystals

“…111.52 In an unprotonated zwitterionic L-histidine, the angle centred around these atoms has a value 112.2° whereas in the protonated LHFB it measures about 108.5°, which is in agreement with L-histidine tetrafluorosuccinate single crystals whose value was reported as 108.5° [15].…”

“…It seems that the vibrational spectra measured at room temperature support such an assumption by giving a strong absorptions at 1523 and 1409 cm -1 for symmetric and antisymmetric stretching vibrations of ionized carboxylate group. The above assignment is similar to L-histidinium tetrafluorosuccinate crystal [15]. Ratajczak et al [12], wrote that the lack of any strong IR band at 1700 cm -1 clearly indicates that L-histidine possess COO -ion and exists in zwitterionic form.…”

“…In particular, L-histidine is an interesting molecule from the crystal engineering as well as supramolecular point of view [6]. The crystallographic data for other L-histidine complexes exists in the literature are salts of L-histidine formate, L-histidine acetate, L-histidine oxalate, L-histidine maleate, L-histidine L-tartarate, L-histidine dihydrogen arsenate orthoarsenic acid, L-histidine perchlorate, L-histidine succcinic acid and L-histidine tetraflurosuccinate [7][8][9][10][11][12][13][14][15]. All of these compounds are stabilized by extensive networks of hydrogen bonds.…”

Crystal growth, thermal and optical studies on phase matchable new organic NLO material for blue-green laser generation

“…We have reported recently on the growth, thermal and optical properties of a semiorganic NLO material Lhistidine tetrafluoroborate (L-HFB) [8] and on the crystal structure of an organic NLO material L-histidinium tetrafluorosuccinate (L-HFS) [9]. In the present investigation, we report on the synthesis of L-histidinium tetrafluorophthalate (L-HFP) and its solubility in two different solvents.…”

Growth, Electrical, Thermal, Optical, Physiochemical and NLO Properties of Dyes Doped Tetrafluoro Phthalate Crystals

“…In recent years, there has been considerable interest on organic materials due to their potential applications such as frequency conversion, optical signal processing, light modulation, optical switching and logic gates [1][2][3] . Semi-organic crystals are suitable for highly aligned and stable orientation of NLO chromophores in the crystal lattice 4 .…”
