Synthesis, Structure and Properties of a Novel Compound with π-π Stacking

在水溶剂中,采用水热法合成了一种π-π堆砌化合物(H2SIP)(4,4’-bipy H)(4,4’-bipy)(Na H2SIP=间苯二甲酸-5-磺酸单钠盐,4,4’-bipy=4,4’-联吡啶)。采用X射线单晶衍射和元素分析等方法对化合物进行了表征。X射线单晶衍射表征结果表明,该化合物晶体属于三斜晶系,空间群为P1。晶体学参数:a=6.8723(7),b=12.0241(12),c=15.7545(16),α=110.136(3)°,β=95.361(3)°,γ=101.438(3)°,V=1179.4(2)3和Z=2。其荧光发射峰在395nm,是分子间电荷转移所致。

A novel compound with π-π stacking （H2SIP）（4,4＇-bipyH）（4,4＇-bipy） （NaH2IP= 5-sulfoisophthalic acid monosodium salt, 4,4＇- bipy = 4,4＇-bipyridine） was synthesized by hydrothermal method in water. It is characterized by X-ray single crystal diffraction and elemental analysis methods. The characterization result of X-ray single crystal diffraction shows that the crystal of the compound crystallized in triclinie system with a space group P1. The unit cell parameters include a=6.8723（7）A^°, b=12.0241（12）A^°, c=15.7545（16）A^°, α=110.136（3）°, β=95.361（3）°, γ=101.438 （3）°, V =1179.4（2）A^°^3 and Z=2. Its fluorescence emission peak is at 395nm, which is caused by intermolecolar charge transfer.
