用 XPS表征 2 -芳胺基 -1 ,3,4 -噻二唑 -5-硫酮 (1 )在ω-溴代 -ω-(1 H-1 ,2 ,4 -三唑 ) -苯乙酮诱导下生成的2 -芳胺基 -3H-1 ,3,4 -噻二唑 -5-硫醇类介离子化合物 (4 ) .结果表明 ,化合物 4分子中的 C1 s,N1 s,S2 p电子结合能均高于化合物 1 ,尤其以 N1 s,S2 p结合能谱最为特征 .例如在含 3个氮原子的化合物 4中由于噻二唑环的两个氮环境不同 ,故产生 3个峰 ,而在与其结构相近的对照物 1中 ,由于噻二唑环的两个氮环境相近 ,故产生 2个峰 .S2 p诸状态结合能加合值化合物 4均大于化合物 1 ,在化合物 4中均是杂环内硫大于杂环外硫 Characterization of 2 - arylamino - 1, 3,4 - thiadiazole - 5 - thione (1) by XPS in ω - bromo - ω- (1 H-1,2,4-triazole) Ketone - induced 2 - arylamino - 3H - 1, 3,4 - thiadiazole - 5 - thiol mesogen compounds (4). The results showed that C1 s, N1 s, S2 p electron binding energy are higher than those of compound 1, especially the binding energy spectrum of N1 s and S2 p.For example, in the compound 4 containing 3 nitrogen atoms, the two nitrogen environments of thiadiazole ring are different, Peak, and in its control structure similar to the 1, due to the thiadiazole ring two nitrogen environment is similar to, so there are two peaks. S2 p state binding energy adduct compound 4 are greater than compound 1, compound 4 In the heterocyclic sulfur are greater than heterocyclic sulfur
