Fullerene receptor based on calix[5]arene through metal-assisted self-assembly

A self-assembled fullerene receptor based on calix[5]arene has been developed. Silver cation complexation held together the two calix[5]arenes with bipyridine units providing a large enough cavity to take up C(60) or C(70). The formation of the supramolecular complex with C(60) or C(70) was established by using the electrospray mass spectrometry. (C) 2001 Elsevier Science Ltd. All rights reserved.
