Synthesis and properties of new fluorenonocrownophanes having a stilbene fragment and their reaction with paraquat
摘要:
New crownophanes containing 2,7-dioxyfluorenone and 4,4'-dioxystilbene fragments linked through di-, three, tetra-, and pentaethylene glycol linkers were synthesized. The formation of pseudorotaxanetype host-guest complexes in reactions of these crownophanes with 1,1'-dimethyl-4,4'-bipyridinium dication was detected by fast atom bombardment mass spectrometry, H-1 NMR, and electron spectroscopy.
