Charge-transfer reactions of C-60 in surfactant-based complex fluid media
MetadataShow full item record
Surfactant-based complex fluid media enables the investigation of charge-transfer reactions between a hydrophobic C-60 molecule and hydrophilic solutes. The formation of a ground state charge-transfer complex between C-60 and ethylamine was demonstrated in an ionic surfactant/water/oil microemulsion, the value for the complexation constant of K = 1.1 M-1 was determined. The one-electron reduction of fullerene occurs in reaction with the excess electrons stored on nanometer-sized metal (Ag) or quantized semiconductor (TiO2) particles in microemulsions.
