Effects of C$_{\bf 60}$ Doping on Electrical and Optical Properties of Poly[(disilanylene)oligophenylenes]

Photoluminescence (PL) of poly[(disilanylene)quaterphenylene] (PDSiQP) has been markedly quenched upon introduction of several mol% of C60, whereas photoconductivity of PDSiQP has been drastically enhanced upon doping with a small amount of C60 at the excitation with a photon energy exceeding the band gap energy of PDSiQP. We interpreted these results taking the electronic energy states of both PDSiQP and C60 and the role of oligophenyl units in the main chain of PDSiQP into consideration.
