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 π-π-stacking compound (H2SIP) (4,4’-bipy H) (4,4’-bipy) (Na H2SIP = 5-sulfo isophthalic acid Acid monosodium salt, 4,4’-bipy = 4,4’-bipyridine). The compounds were characterized by X-ray single crystal diffraction and elemental analysis. X-ray diffraction characterization results show that the crystal belongs to the triclinic system, space group P1. Crystallographic parameters: a = 6.8723 (7) , b = 12.0241 (12) , c = 15.7545 (16) , α = 110.136 (3) °, β = 95.361 (3) °, °, V = 1179.4 (2) 3 and Z = 2. The fluorescence emission peak at 395nm, is due to intermolecular charge transfer.
