Research object - crownophanes containing the fragments of fluorene, hydroquinone, 4,4'-dihydroxybiphenyl and 1,5-dihydroxynaphtalene joined by the residues of polyethylene glycols. A purpose of work is synthesis of new crownophanes containing the fragments of fluorene, hydroquinone, 4,4'-dihydroxybiphenyl and 1,5-dihydroxynaphtalene, joined by the residues of polyethylene glycols, the study of their structure, properties and interaction with electron deficient molecules. Research methods - synthetic, UV, NMR, fluorescence spectroscopy, mass spectrometry, X-ray. Fluorenocrownophanes containing fluorene, biphenyl or hydroquinone fragments linked polyether chains of various lengths were prepared by the hydrogenation of fluorenonocrownophanes in the presence of a palladium catalyst. For fluorenocrownophanes with a fragment of naphthalene satisfactory results were achieved by Kishner-Wolff reduction of fluorenonocrownophanes by hydrazine hydrate. X-ray analysis of crystals of bis(fluoreno) crownophane in which the fluorene fragments linked by residues of tetraethylene glycol were carried out. Fluorescence titration showed that the obtained fluorenocrownophanes form stable inclusion complexes with electron deficient organic molecules. The most stable complexes with all crownophanes observed for 2,4,7-trinitrofluorenone.
