Abstract :
Molecular tweezers based on calix[4]arene- or thiacalix[4]arene–porphyrin conjugates have been prepared starting from tetraformyl calixarenes and aminoporphyrin moieties. As proven by NMR and UV/vis titration experiments, these compounds form 1:1 complexes with C60 and C70 fullerenes in solution while possessing a high selectivity towards fullerene C70.
