A Novel [60]Fullerene-Calixarene Conjugate Which Facilitates Self-Inclusion of the [60]Fullerene Moiety into the Homooxacalix[3]arene Cavity

Nucleophilic cyclopropanation of [60]fullerene by the addition–elimination mechanism

“…The separately prepared hydroxy-containing fullerene block 238 was fused by the carbodiimide method with the homooxacalix [3]arene moiety to give compound 239, which exhibits interesting selfcomplexation-decomplexation properties in response to the solvent polarity (Scheme 67). 126 A macrocycle having two isosteviol moieties and malonate fragment was synthesized and its ability to inhibit the growth of Mycobacterium tuberculosis H37Rv in vitro at a minimum concentration of 1 mg  cm À3 was demonstrated. The macrocycle and the acyclic analogue add fullerene C 60 at the activated methylene group to furnish the corresponding methanofullerene conjugates 240 and 241 (Scheme 68).…”

Fullerenes: Multitask Components in Molecular Machinery

“…Fullerenes and especially C 60 have been widely studied and today are valuable building blocks for the preparation of materials with potential applicability in different technological fields including photovoltaics, nonlinear optics, optoelectronics, and medicine 16–19. Also, they have found applications in molecular machines based on calixarenes 20–22. The properties of fullerenes derive from the three‐dimensional structure of their extended π system that makes them excellent electron acceptors and chromophores.…”

Fullerene: vielseitige Bausteine für molekulare Maschinen

“…B. in Photovoltaik, nichtlinearer Optik, Optoelektronik und Medizin 16–19. Sie haben auch den Weg in molekulare Maschinen auf Calixaren‐Basis gefunden (Schema ) 20–22. Die meisten Funktionen, durch die Fullerene bekannt wurden, sind auf ihre ausgedehnten π‐Systeme zurückzuführen.…”
