Twelve calixarene derivatives (18R) with different para-substituents (R) were synthesized and applied to selective precipitation of C60 and C70 from benzene and toluene. 18Pri and 18But precipitates from benzene and toluene, forming a 1:1 complex with C60 whereas only 18But precipitates from benzene, forming a 1:2 18But/C70 complex. The spectroscopic studies of the precipitate complexes are also reported.
