Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Angewandte Chemie, International Edition called Chirality-Dependent Second-Order Nonlinear Optical Effect in 1D Organic-Inorganic Hybrid Perovskite Bulk Single Crystal, Author is Fu, Dongying; Xin, Jianli; He, Yueyue; Wu, Shichao; Zhang, Xinyuan; Zhang, Xian-Ming; Luo, Junhua, which mentions a compound: 334618-07-4, SMILESS is Cl.Cl.N[C@H]1CCCNC1, Molecular C5H14Cl2N2, Name: (S)-Piperidin-3-amine dihydrochloride.
The introduction of chirality into organic-inorganic hybrid perovskites (OIHPs) is expected to achieve excellent photoelec. and nonlinear materials related to CD. Owing to the existence of asym. center and intrinsic chirality in the chiral OIHPs, the different efficiencies of second harmonic generation (SHG) signal occurs when the circularly polarized light (CPL) with different phases passes through the chiral crystal, which is defined as second harmonic generation CD (SHG-CD). Here, the SHG-CD effect is developed in bulk single crystals of chiral one-dimensional (1D) [(R/S)-3-aminopiperidine]PbI4. It is the first time that CPL is distinguished using chirality-dependent SHG-CD effect in OIHPs bulk single crystals. Such SHG-CD technol. extends the detection range to near IR region (NIR). In this way, the anisotropy factor (gSHG-CD) through SHG-CD signal is as high as 0.21.
