Circular dichroism of optically active organometallic derivatives of fullerenes C60 and C70

Abstract

Palladium and platinum complexes of fullerenes C 60 and C 70 containing the axially chiral ligand (-) BITIANP (BITIANP is 2,2´ bis(diphenylphosphino) 3,3´ bi(benzo[b]thiophene)) and pyrrolidino[60]fullerene bearing a planar chiral organometallic π complex substituent in the heterocyclic ring were studied by circular dichroism (CD) spectroscopy.

Homo‐ and methano[60]fullerenes with chiral attached moieties – 1H and 13C NMR chemical shift assignments and diastereotopicity effects

“…[1] Fullerene derivatives containing chirality centers attached are quite promising because of their practical application in medicine and optics. [2][3][4][5][6][7][8][9][10][11][12][13][14][15] Among physicochemical methods, which are used for studying properties of fullerenes, NMR spectroscopy occupies a leading position. [16] The 13 C chemical shifts of fullerenes contain information about the type of the electron density distribution into the fullerene core.…”
