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 (Pt₀̣ 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 he efficiency of PCT in MEH-PPV/(Pt₀̣.₇₅C₆₀)n blend is somewhat less than in MEH-PPV/C₆₀. This difference is attributed to more enhanced phase separation in MEH-PPV/(Pt₀̣.₇₅C₆₀)n at the nanoscale. Meanwhile, our photocurrent data imply that (Pt₀̣.₇₅C₆₀)n chains could provide a network for collection of photoinduced charges. Remove selected
