合成了2,2-二氯-1,3-苯并二氧噁茂(DCBZ),并用得到的DCBZ与对硝基酚反应得到2,2-二(对硝基苯氧基)-1,3-苯并二氧噁茂(DPBZ).对DPBZ用IR、1HNMR进行表征并培养出单晶,经X射线衍射法确定了其晶体结构,R=0.0414,Rw=0.1044.晶体结构表明,晶体属于单斜晶系,P2(1)/c空间群,晶胞参数:a=15.7093(4)nm,b=8.7799(2)nm,c=13.5336(3)nm,β=102.840(2)°,V=1819.96(7)nm3,Z=4.化合物通过分子间的弱氢键作用和π-π堆积形成超分子结构,分子中2个对硝基苯氧基分别处于胡椒环平面的两边.图6,表4,参16.
2,2-dichloro-1,3-benzodioxole (DCBZ) was synthesized and reacted with p-nitrophenol using DCBZ to give 2,2-bis (p- nitrophenoxy) (DPBZ). The DPBZ was characterized by IR and 1HNMR and the single crystal was characterized by X-ray diffraction, R = 0.0414, Rw = 0.1044. The crystal structure showed that the crystal Belongs to the monoclinic space group P2 (1) / c, with unit cell parameters of a = 15.7093 (4) nm, b = 8.7799 (2) nm, c = 13.5336 , V = 1819.96 (7) nm3 and Z = 4. The compounds formed supramolecular structure through the weak intermolecular hydrogen bonding and π-π stacking, and the two p-nitrophenoxy groups in the molecule were on the two sides of the pepper ring.
