摘要 合成了2种对苯二胺类西佛碱(Ⅰ)和(Ⅱ),西佛碱(Ⅰ)含有氢键,而(Ⅱ)没有。同时合成了4种中间体(Ⅰ-a、Ⅰ-b与Ⅱ-a、Ⅱ-b)。通过1H NMR、13C NMR和MS确定了6种化合物的结构。研究了化合物(Ⅰ)和(Ⅱ)的光谱特性。结果表明,具有氢键的化合物可以增加分子的共平面性,双光子化合物的吸收截面(δ=14744GM)提高很大,说明分子内的氢键作用对化合物的TPA系数产生很大的影响。 Two kinds of p-phenylenediamine schiff base (Ⅰ) and (Ⅱ) are synthesized. Schiff base(Ⅰ) con- tains hydrogen bonds and (Ⅱ) does not. At the same time, four kinds intermediates (Ⅰ-a, Ⅰ-b and Ⅱ-a, Ⅱ-b) are synthesized and characterized by ^1H NMR, ^13C NMR, MS and the compounds (Ⅰ) and ( Ⅱ) spectral characteristics are studies. The results indicate that the hydrogen bonds of compound can increase coplanarity and improve two-photon absorption cross-section(δ= 14744GM). Intrahydrogen-bond compounds have a significant effect on factor of the TPA.
