【摘要】 本文用 XPS 研究了十四种芳基重氮盐及其与18-c-6(1)和二苯并-24-c-8(2)的配合物.结果表明,重氮盐中α-N1s 和β-N1s 结合能的化学位移大小与 R 有关.重氮盐与冠醚以β-N 向醚氧提供电子(β-N→O)而配位的,而醚氧 O1s 结合能降低多少似可反映配合物的稳定性.更多还原

【Abstract】 The complexes of fourteen substituted aryldiazonium salts RC₆H₄N₂⁺BF₄^-（R=H,p-CH₃,p-NO₂,p-Ⅰ,p-Vl,p-F,m-Br,m-Cl,m-CH₃,o-CH₃,o-OCH₃,o-NO₂,o-Br,o-Cl）with crown ethers 18-c-6（1）and dibenzo-24-c-8（2）have been studied by XPS.The results show that the chemical shifts of α-Nls and β-Nls of substitutedaryldiazonium salts are closely related to the induction and conjugation effects of Rgroups.It is interesting to note that charge transfer（β-N→O）take place uponcomplexation of substituted aryldiazonium salts with crown ethers.Therefore thedecrease of binding energy of crown ether oxygen may be used as a measure of thestabilities of these comphlexes.更多还原
