双百草枯衍生物中以苯为中心的两个百草枯基团的夹角对冠醚与双百草枯络合的影响

摘要

A crown ether 5 and three bisparaquats derivatives with different angles (A180, A120 and A60) were designed and synthesized. The angle of two parapuat groups in the central benzene of the bisqaraquat derivatives played a significant role in the complexation of the crown ether 5 with the bisparaquat derivatives. Computational quantum chemistry also proved the above results. The crown ether 5 showed selective recognition on the above three guests.%设计并合成了一种新颖的冠醚5和3种有着不同夹角(A180、A120和A60)的双百草枯衍生物.双百草枯衍生物中以苯为中心的两个百草桔基团间的夹角的作用表现为:冠醚5对类双百草枯的络合有着显著的影响.量子化学计算也论证了这一结果.冠醚5对上述3种类双百草枯有着选择性识别作用.
