激子手性方法用于双冠醚配合物结构的研究
APPLICATION OF EXCITON CHIRALITY METHOD TO THE STUDIES OF DOUBLE CROWN ETHER COMPLEXES OF KETONIC ESTER TYPE
【摘要】 本工作以氯仿-乙醇(1∶1)为溶剂,室温下测定了酯酮型双冠醚(I-V)与碱金属盐MX形成配合物后的圆二色性(CD);依激子手性方法,推测出了配合物的右手螺旋扭变结构,系统命名为P型绝对立体化学,并由其圆二色性确定了冠醚与金属离子的配位比.
【Abstract】 Circular dichroism (CD) of double crown ether complexes of ketonic ester type with MX were measured in CHCl3-EtOH (1:1 ) solution at room temperature. The right -handed screwn structure were deduced according to exciton chirality, i.e.P absolute configuration with negative Exciton Chirality. The Coordination ratios of M+ and ethers were detetermined from CD.
