The exploration of the crystal nucleation parameters and physico-chemical analysis of a single crystal: 2-amino-4,6-dimethoxypyrimidinium hydrogen (2R,3R)-tartrate 2-amino-4,6-dimethoxypyrimidine

“…The kinetic functions such as the Arrhenius constant, the enthalpy of activation, the entropy of activation and the Gibb's free energy change of decomposition were governed by the following relationships. For solid state reactions, a thermogravimetric kinetic mechanism of decomposition was determined by measuring fractional mass loss using a conversion process ( α c ) and the degradation rate could be accurately obtained from the Arrhenius relationship: 21 where W is the actual mass at any degradation time (mg), W 0 is the initial mass (mg) and W f is the final mass at the end of thermal degradation process (mg), k is the rate constant, A is the Arrhenius constant, E a is the activation energy, R is the gas constant and T is the temperature (K). The plot between inverse of T and log 10 [{1 − (1 − α ) 1− n }/{ T 2 (1 − n )}] in Fig.…”

Novel Metal–Organic Framework and Crystal Engineering of Bismorpholinium Mercury(II) Tribromo Chloride (BMMC) for Optoelectronic Applications

“…Nowadays, organic crystals with a large order of nonlinear coefficients are always emerging and have been attracted for various applications that include high-speed data processing, electro-optic modulation, frequency conversion, lasers, optical limiting, terahertz generation, and terahertz detection. − Usually, the organic single crystals consist of π-conjugated electron multiple donor and acceptor groups, short multiple hydrogen bonding between donor and acceptor, and strong nonlinear optical (NLO) chromophores, which leads to the large nonlinear optical coefficients and inherent ultrafast optical response as compared with the inorganic materials. For instance, organic single crystals of N , N -dimethylamino were commercialized in optical, frequency conversion as well as detection and THz generation applications due to the existence of multifunctional properties that originated through the emphatic alignment of molecular structure. − The organic molecule is more favorable to adjust the chemical structure precisely for the intended usages including optical computing, optical limiting for the sensor fabrication, optical switching, and so on . Good-quality NLO single crystals with inherent high nonlinearity are needed to develop the latest photonic and optoelectronic devices.…”

Study of the Crystalline Perfection, Homogeneity, Chemical Etching on the Surface, and Third‐Order Nonlinear Optical Properties of (1 1 0) Oriented Hydroxyethylammonium D‐Tartrate Monohydrate Single Crystal and Hirshfeld Surface Analysis

“…As a result, organic NLO materials are needed to be grown as large‐sized single crystals with high NLO efficiency. [ 11–16 ] Some organic compounds contain amine functional group (HNH), which leads to the assumption that they have good SHG and optical characteristics. [ 17 ] Hydroxyethylamine is an organic molecule that has amine and hydroxyl (OH) groups.…”
