experimental part, p. 17 - 23 (2011/08/04)
The synthesis of monomers and dimers of some new crown ether type macrocycles with 1,4-phenylene and 1,4-naphthylene units are reported. The structural investigations of the compounds were carried out by NMR spectra, MS measurements and the single crystal X-ray solid state molecular structure of one compound.
