non-equivalence of the NH2 hydrogens evidences the iminium character of this moiety. Compound 1, exploiting strong H-bonds, self-assembles generating supramolecular linear tapes. Theoretical calculations are in good agreement with experimental solid state and solution data. Electronic properties of 1 (lowest lying excitation energies and corresponding oscillator strength) have also been determined by time dependent
新衍生品 2-氨基-4-氯-6-吡唑基-[1,3,5]三嗪,1,通过反应制备2-氨基-4,6-二氯-[1,3,5]三嗪 与过量 吡唑通过1 H,13 C和15 N NMR测量和单晶XRD结构测定来表征。NH 2氢的非等价性证明了该部分的亚铵盐特征。化合物1,利用强氢键,自组装产生超分子线性带。理论计算与实验固态和溶液数据非常吻合。电子特性1(最低的激发能和相应的振荡器强度)也已通过在PBE级别上随时间变化的DFT确定。
