  Enantioselective hydrolysis of an α-amino acid ester in sugar-derived surfactant micelles

  摘要：

  p-Nitrophenyl ester of D-phenylalanine hydrogen bromide was hydrolyzed much faster than that of the corresponding L-isomer in the micelles formed with sugar-derived surfactants such as N-dodecylmaltobionamide. The enantioselectivity was largely affected by the alkyl chain length as well as the structure of the sugar part of the surfactant. (C) 1998 Elsevier Science Ltd. All rights reserved.

  L-Phenylalanine L-phenylalaninium bromide (LPLPB), an amino acid non-centrosymmetric crystal having a large second harmonic generation (SHG) efficiency, being 4.5 times that of KH2PO4 (KDP), has been successfully grown using a slow evaporation method employing a temperature gradient technique. The structure of the grown crystal was solved and refined by single-crystal X-ray diffraction, and this demonstrates that it belongs to a monoclinic system with the space group P21. The confirmation of its functional groups was recorded using Fourier transform infrared spectroscopy. Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) were used to study its thermal properties. The optical behaviour was examined and its optical constants were determined by UV-vis analysis. Dielectric spectroscopy reveals the dielectric nature of the grown crystal. The mechanical strength of the grown LPLPB was estimated by microhardness studies, and the Young's modulus of the grown LPLPB was calculated to be 3.310 × 1010 N m−2.

  L-苯丙氨酸 L-苯丙氨酸溴化物（LPLPB）是一种氨基酸非中心对称晶体，具有较大的二次谐波生成（SHG）效率，是 KH2PO4（KDP）的 4.5 倍，已经成功地采用一种利用温度梯度技术的缓慢蒸发方法生长出来。通过单晶 X 射线衍射解决了生长晶体的结构并进行了优化，这表明它属于单斜晶系，空间群为 P21。利用傅立叶变换红外光谱记录了其官能团的确认。热重分析（TGA）和差示扫描量热法（DSC）用于研究其热性质。通过紫外可见光分析检查了其光学行为并确定了其光学常数。介电光谱揭示了生长晶体的介电性质。通过显微硬度研究估计了生长 LPLPB 的机械强度，并计算出生长 LPLPB 的杨氏模量为 3.310 × 1010 N·m-2。
