在光诱导下会改变结构的化学物质不仅能成为贮存光能的化学容器,而且能作为光能转化的介体。螺旋苯并吡喃和偶氮苯的衍生物都是这种可供选择的物质。我们研究的目的是利用光诱导的偶氮苯的顺、反异构现象来控制冠醚族化合物的功能。我们报导了光辐射影响一种萃取平衡。这种平衡是用偶氮苯挢联的冠醚作的碱金属碱阳离子在水与苯之间的萃取平衡。在本文中我们报导一种叫做“光-蝶(Photobutterfly)冠醚”的新奇的双冠醚。这种冠醚因光辐射而改变萃取性能。
Chemicals that change their structure under photoinduced light can not only act as a chemical reservoir for storing light energy, but also as a mediator of light energy conversion. Helical benzopyrans and azobenzene derivatives are all examples of this alternative. The purpose of our study is to control the function of the crown-ether compounds by utilizing the cis- and trans-isomerism of light-induced azobenzenes. We reported that light radiation affects an extraction balance. The balance is the equilibrium between the water and the benzene extracted with the alkali metal base cations of the azobenzene couple crown ethers. In this article we report a novel double-crown ether called “Photobutterfly Crown Ether”. This crown ether changes its extraction properties due to light radiation.
