摘要：

Photoluminescence (PL) of poly[(disilanylene)quaterphenylene] (PDSiQP) has been markedly quenched upon introduction of several mol% of C-60, whereas photoconductivity of PDSiQP has been drastically enhanced upon doping with a small amount of C-60 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 C-60 and the role of oligophenyl units in the main chain of PDSiQP into consideration.
