| description | The new fullerene dimer adduct PCBM-C
120O was studied as an electron acceptor by light-induced ESR (LESR) when blended with the electron donor-conjugated polymer M3EH-PPV in a thin solid film. ESR parameters for the PCBM-C
120O anion radical and the M3EH-PPV polaron (triaxial
g
x,
y,
z
factors) were determined by X- and K-band ESR techniques at temperatures of 77 and 120
K. It was found that isotropic
g
0 of PCBM-C
120O anion radical ESR spectra obtained in this blend under illumination is close to
g-factors of electrochemically reduced (C
120-O)
−
and does not coincide with the analogous parameter of (C
120-O)
2−
(reported in literature). Spin relaxation parameters (
T
1 and
T
2) of the PCBM-C
120O anion radical and M3EH-PPV positive polaron are similar to
T
1,
T
2 for light-induced ion radicals in the P3HT/PCBM blend. |
