摘要

成功合成了一种新的氨基酸基晶体[3PyAla][BF4]，并用单晶衍射对其进行了表征。标题盐在极性、压电P21空间群中结晶。压电显微镜（PFM）表明，[3PyAla][BF4]的压电响应与铌酸锂（LiNbO3）相当。研究了丙氨酸衍生物的晶体结构（特别是氢键网络）与物理性质之间的关系。此外，通过热重分析（TGA）对其热行为进行了研究。讨论了[3PyAla][BF4]和其他丙氨酸盐的压响应。

Crystal structure and piezoelectric properties of the final member of the pyridylalanine derivative series: [H-β-(3-pyridyl)-Ala-OH][BF4]

A new amino acid-based crystal, [3PyAla][BF₄], was successfully synthesized and characterized using single-crystal diffraction. The title salt crystallizes in the polar, piezoelectric P2₁ space group. Piezo-electric force microscopy (PFM) demonstrated that the piezoresponse of [3PyAla][BF₄] is comparable to that of lithium niobate (LiNbO₃). The correlation between the crystal structure – particularly the hydrogen bond network – and the physical properties of this alanine derivative was examined. Additionally, its thermal behavior was investigated through thermogravimetric analysis (TGA). The piezoresponse of [3PyAla][BF₄] and other alanine salts was discussed.
