- Аннотация: Photoinduced charge transfer (PCT) in donor-acceptor blends of poly[2-methoxy-5-(2‘-ethyl-hexyloxy)-1,4-phenylene vinylene] (MEH-PPV) with coordination oligomer (Pt0,75C60)n has been studied and compared with that in MEH-PPV/C60 blends. The blends were investigated by using optical absorption, scattering, photoluminescence (PL), photoinduced absorption (PIA), and photocurrent action spectroscopies. We have found that as an electron acceptor (Pt0,75C60)n demonstrates the efficiency of PCT somewhat less than C60. This difference is attributed to more enhanced phase separation in MEH-PPV/Pt0,75C60 at the nanoscale. Meanwhile, our photocurrent data suggest that (Pt0,75C60)n can provide an effective network for collection of photoinduced charges.
