These methods allow to receive target compounds with a specific structure, including the conformation of macrocyclic molecules, with high yields. With the help of methods of NMR specrtoscopy and spectrofotometry the data on ability of the calix[8]arene crown ethers to form complexes with cations of alkaline metals, the properties of homo- and heterobinuclear complexes of lantanides with p-tert-butylcalix[8]arene and the properties of complexes calix[4]arene crown ethers with terbium ion are investigated Product Description popup.authors popup.nrat_date 2020-04-02 Close
