摘要:
Novel C-60-fused isoxazolines have been synthesized by using 1,3-dipolar cycloadditions of pyrazole nitrile oxides, generated in situ, to C-60 under thermal or focused microwave irradiation. The cyclic voltammetry measurements show a strong donor pyrazole ring and a better acceptor ability of the fullerene moiety compared to pristine C-60 The UV-Vis and H-1 NMR spectra suggest a weak CT interaction in the ground state.
