摘 要:利用两种柔性联吡啶胺分子M1和M2(M1=N-[(3-吡啶基)甲基]-3-吡啶胺,M2=N-[(4-吡啶基)甲基]-3-吡啶胺)分别与高氯酸反应,得到了超分子化合物HM1+·ClO-4(1)和HM2+·ClO-4(2),并对它们进行了元素分析、红外、热重、荧光、粉末及单晶X射线衍射等表征。化合物(1)属于单斜晶系,P21/c空间群,a=0.734 21(15)nm,b=1.186 0(2)nm,c=1.492 0(3)nm,β=92.54(3)°,V=1.298 0(5)nm3,Z=4,R=0.059 7。化合物(2)属于单斜晶系,P21/n空间群,a=0.972 87(19)nm,b=1.308 9(3)nm,c=1.009 1(2)nm,β=95.46(3)°,V=1.279 2(4)nm3,Z=4,R=0.088 9。在两种化合物中,柔性联吡啶胺分子均发生了单质子化,并且存在非共价键作用力,如anion…π作用、氢键和π…π堆积作用,形成了不同结构的超分子晶态网络。此外,荧光分析结果表明,高氯酸根离子构筑的超分子晶态网络化合物表现出较强的蓝光发射。CCDC:950660;950661。Reactions of two flexible bis ( pyridyl ) amines M 1 and M2 ( M 1 = N- ( pyridin-3-ylmethyl ) pyridin-3-a- mine, M2 = N-(pyridin-4-ylmethyl)pyridin-3-amine) with perchloric acid produced two supramolecular compounds, HM1+ · ClO4^- ( 1 ) and HM2 ^+· CIO4 (2) , respectively, which were characterized by elemental analysis, IR, TG, PL, powder and single-crystal X-ray diffraction. Compound ( 1 ) crystallizes in a monoclinic system with space group P21/c and parameters : a=0.73421(15) nm, b=1. 1860(2) nm, c=1.4920(3) nm,β= 92.54 (3) °, V = 1. 298 0 (5) nm^3, Z = 4, R = 0. 059 7. Compound (2) crystallizes in a monoclinic system with space group P21/n and parameters: a =0. 972 87(19) nm, b = 1. 308 9(3) nm, c = 1. 009 1 (2) nm, fl = 95.46 (3) °, V = 1. 279 2 (4) nm 3, Z = 4, R = 0. 088 9. In these two supramolecules, the flexible bis( pyri- dyl) amine molecules are mono protonated and diverse supramolecular patterns are obtained with the assistance of various non-covalent interactions, such as hydrogen bonds, π…π stacking, as well as anion…π interactions. Moreover, the networks constructed from the perchlorate exhibit strong blue light emission at room temperature. CCDC : 950660 ; 950661.
