Lipophilic bis(crown ethers) containing 15-crown-5 and 18-crown-6 rings were synthesized so as to obtain excellent neutral carriers for K+- and Cs+-selective electrodes, respectively. The K+-selective electrode based on the dodecylmethylmalonate of bis (15-crown-5), (I)(n= 1, R = Me), exhibited eminent electrode properties, proving of great practical use, while the Cs+-selective electrode of the bis(18-crown-6)
合成了包含15-cro-5和18-cro-6环的亲脂性双(冠醚),从而分别获得了对K + -和Cs + -选择电极优异的中性载流子。基于双(15-crown-5)(I)(n = 1,R = Me)的十二烷基甲基丙二酸酯的K +-选择性电极表现出卓越的电极性能,被证明具有很大的实际用途,而Cs +-选择性电极双(18-crown-6)衍生物(I)的电极(n = 2,R = Me)不能得到预期的结果。K个的电化学选择性+电极基于双(15-冠-5),(I)(的dodecylmalonate Ñ= 1,R = H),还讨论了十八烷酰氧基甲基-15-冠-5(II)。
