摘要

手性杂化金属卤化物由于其不对称结构,在下一代光电器件的发展中具有很大的前景。本文制备了一系列非中心对称结构的一维手性卤化铅杂化物,包括(R/S- c12h20n2)2Pb4I12·4H2O、(R/S- c12h20n2)SbI5和(R/S- c12h20n2)BiI5 ([R/S- c12h20n2]2+分别为(R)-3-氨基-1-苄基哌啶和(S)-1-苄基-3-氨基哌啶阳离子)。(R-C12H20N2)2Pb4I12·4H2O的二次谐波生成(SHG)是KH2PO4的3.3倍。用Sb或Bi代替Pb后,(R/S-C12H20N2)XI5 (X = Sb, Bi)的SHG强度略有降低,结构也向高空间群转变。此外,(R/S-C12H20N2)SbI5在暴露于溶剂(H2O)时表现出从红色到黄色的快速可逆非晶化诱导的颜色转变,突出了其在传感和防伪技术中的应用潜力。这些发现表明,R/S-C12H18N2系列晶体是激光应用的有希望的候选人,在水检测,防伪和信息加密方面具有潜力。

Chiral organic hybrids for nonlinear optical applications and solvent-induced reversible red–yellow color change†

Chiral hybrid metal halides hold great promise for the development of next-generation optoelectronic devices, owing to their asymmetric structures. Here, a series of one-dimensional chiral lead-halide hybrids with non-centrosymmetric structures were developed, including (R/S-C12H20N2)Pb2I6·2H2O, (R/S-C12H20N2)SbI5, and (R/S-C12H20N2)BiI5 (where [R/S-C12H20N2]2+ refers to (R)-3-amino-1-benzylpiperidine and (S)-1-benzyl-3-aminopiperidine cations). (R-C12H20N2)Pb2I6·2H2O exhibits second harmonic generation (SHG) 3.3 times that of KH2PO4. Replacing Pb with Sb or Bi results in a slight reduction in the SHG intensity compared with (R/S-C12H20N2)XI5 (X = Sb, Bi) and a transition to a higher-symmetry space group. Furthermore, (R/S-C12H20N2)SbI5 exhibits a rapid and reversible amorphization-induced color transition from red to yellow upon exposure to a solvent (H2O), highlighting its potential for applications in sensing and anti-counterfeiting technologies. These findings suggest that the R/S-C12H18N2 series crystals are promising candidates for laser applications and hold potential in water detection, anti-counterfeiting, and information encryption.
