Abstract
The present work describes the one-pot synthesis of new polyazamacrocy clic compounds 4-7 having hydrophobic hosts cavities (beta-cyclodextri ns) attached to a metal chelating aza-macrocycle by ureido spacer arms . A coupling average of 30% was obtained, proving the efficiency of th e ''phosphinimine'' method for a rapid access to new supramolecular de vices. The subsequent complexation of 6 with EuCl3 give the stable com plex 8. Preliminary results on fluorescence properties are reported. ( C) 1998 Elsevier Science Ltd. All rights reserved.
