A novel tetra-crowned cleft 1 has been synthesized and characterized spectrally, and its ability to extract and to transport alkali metal cations has been studied. Compound 1 generally displays greater affinity toward such cations, particularly K+ and Rb+, than do equivalent concentrations of either benzo-15-crown-5 or 2,3-naphtho-15-crown-5. The results obtained from alkali metal picrate extraction
合成了一种新型的四冠裂隙1,并对其光谱进行了表征,并研究了其提取和运输碱金属阳离子的能力。与等浓度的苯并-15-冠-5或2,3-萘-15-冠-5相比,化合物1通常对这些阳离子,尤其是K +和Rb +表现出更大的亲和力。从碱金属苦味酸盐提取和碱金属高氯酸盐运输研究两者获得的结果表明,在空间上邻近苯并-15-冠-5 moieities在1可以与来宾阳离子协同相互作用,由此形成“三明治”复合物。
