| 摘要: 在原位水热条件下，单一手性有机配体(S)-甲基-2-(4-氰基苯胺)-3-(4-羟基苯)丙酸甲酯与叠氮化钠和氯化锌反应，得到了一个新的四唑锌配位聚合物{[Zn(TBHPA)H2O]·H2O}n(1，TBHPA=(S)-2-(4-(2H-tetrazol-5-yl)benzylamino)-3-(4-hydroxy-phenyl) propa-noic acid)。单晶结构表明该化合物结晶在手性空间群P212121，CD谱进一步证实该化合物固体粉末具有单一手性。倍频实验结果表明化合物1的SHG(倍频效应)响应大概是尿素的0.6倍。荧光测定结果显示该化合物在428 nm处有较强的荧光发射峰(激发波长319 nm)。另外，还研究了化合物1在室温条件下不同频率的介电常数变化。 |

| Abstract: A tetrazole-based Zn(Ⅱ) coordination polymer, {[Zn(TBHPA)H2O]·H2O}n(1) (TBHPA=(S)-2-(4-(2H-tetrazol -5-yl)benzylamino)-3-(4-hydroxy-phenyl) propanoic acid), was synthesized by in situ reaction of homochiral ligand (S)-methyl-2-(4-cyanobenzylamino)-3-(4-hydroxyphenyl)propanoate, ZnCl2 and NaN3 under hydrothermal conditions. Single crystal X-ray determination shows that compound 1 crystallize in chiral space groups P212121 and the solid state CD spectrum of further indicate the compound 1 is homochiral. The experimental result indicates that 1 has SHG (second harmonic generation) active with approximate responses 0.6 times that of urea. Fluorescent analysis shows it exhibits one intense emission band at 428 nm when the exciting radiation is set at 319 nm. Dielectric constant of compound 1 were measured at different frequencies at room temperature. CCDC: 824889. |
