| 摘要: |
| 合成了一种新的西佛碱配体N,N'双水杨醛缩二氨基乙醚,并采用x射线单晶衍射法测定了它的晶体结构。该晶体属正交晶系空间群Pbcn,a=5.667(2)Å,b=9.192(3)Å,c=31.829(11)Å,v=1658.2(7)Å3,分子式为C18H20N2O3,Mr=312.36,Z=4,DC=1.251g·cm-3,晶体结构测定和UV,IR谱均表明分子内形成氢键。在甲醇溶液中有一个荧光发射带,λmax=443nm。 |

| Abstract: |
| The title compound was synthesiged and the crystal structure was deternimed by single crystal x-ray diffraction, showing that the crystal was orthorhombic with space group Pbcn,a=5.667(2)Å,b=9.192(3)Å,c=31.829(11)Å,v=1658.2(7)Å3,C18H20N2O3,Mr=312.36,Z=4,Dc=1.251 g·cm-3,The UV-VIS spectra of the title compound in methanol with various concentration were studied and the influence by adding NaOH was observed.The results showed that there exitsed intra-molecular hydrogen-bonding in the title compound.The fluorescence spectra were observed with λmax=443 nm。 |
