两个新型呋喃酰腙的合成、晶体结构与荧光性

以2-呋喃甲醛、肉桂醛、水合肼为原料合成2个含有呋喃环的新型酰腙，即双（2-呋喃亚甲基）腙（L1）和肉桂醛-2-呋喃甲酰腙（L2），并用元素分析、核磁共振、红外、紫外、X-射线单晶衍射和荧光光谱等手段对其进行表征．结构分析表明，酰腙L1属于正交晶系，空间群Pbca，晶胞参数a=0．6S83（7）nm，b=0．9026（8）nm，c=1．5136（14）nm，α=β=γ=90°,V=0．9404（15）nm^3，Z=4；酰腙L2也属于正交晶系，空间群Pbca，a=1．1297（12）nm，b=0．7388（7）nm，c=2．907（3）nm，α=β=γ=90°,V=2．427（4）nm^3，Z=8．荧光性测试表明酰腙L1具有微弱的荧光性，酰腙L2具有强的荧光性．

Synthesis,crystal structure and fluorescence of two novel furan acylhydrazones

Two novel hydrazones containing furan which called bis （2-furyl） methylhydrazone （L1） and cinnamaldehyde-2-furoylhydrazone （L2） were synthesized from 2-furaldehyde, cinnamaldehyde and hydrazine hydrate. They were characterized by using EA,1H NMR, FT-IR,UV, X-ray and fluorescence spectroscopy methods. Structure analysis showed that the acylhydrazone L1 belongs to orthorhombic, space group Pbca, with unit cell parameters a=0.6S83（7）nm,b=0.9026（8）nm,c=1.5136（14）nm,α=β=γ=90°,V=0.9404（15）nm^3,Z=4;and the acylhydrazone L2 also belongs to orthorhombic, space group Pbca,a=1.1297（12）nm,b=0.7388（7）nm,c=2.907（3）nm,α=β=γ=90°,V=2.427（4）nm^3,Z=8. Fluorescence test showed the acylhydrazone L1 has very weak fluorescence,but the acylhydrazone L2 has strong fluorescence.
