Self-assembly of rectangles via building units bearing salen and oxazoline ligands
摘要:
Rigid spacer-chelator with the framework of 3 has been prepared. Building units with two parallel coordination sites such as salen and oxazoline units have also been synthesized. The spacer-chelators, 11 and 15, readily self-assembled with metal complexes such as Zn++ and Co++ to form molecular rectangles. The overall dimensions of the rectangles, 13 and 17, are 6.2 angstrom x 23.5 angstrom. The characterization of the supramolecules by NMR, mass spectroscopy, and X-ray crystal structures is also reported. (c) 2006 Elsevier B.V. All rights reserved.
