Synthesis of allyl-bearing dendrimers with a resorcinarene core and their supramolecular complexes with fullerene C60.
Dendritic branches of poly(arylether) with peripherial allyl chains have been attached to a resorcinarene core. Dendrimers of first, second, and third generation were synthesized. Viability to form supramolecular complexes with fullerene C60 was studied with three dendrimers of first, second, and third generation. All the compounds were characterized by 1H, 13C NMR, FTIR, UV-vis spectroscopy, MALDI-TOF, FAB+ mass spectra, and elemental analysis. Strong pi-pi, CH-pi, and n-pi interactions between the dendrimers and the fullerene C60 were detected in the supramolecular complexes by UV-vis, FTIR, and 13C CP-MAS NMR.
