Novel pyrene derivative conjugated with dimethylsilyl moiety was prepared from bromopyrene. The compound was successfully converted to the corresponding phosphoramidite derivative and incorporated into oligoDNA. In uv-melting study, the resulted fluorescent oligoDNA can discriminate one-base mismatched complement only when the mismatched base is positioned around the middle of the duplex-forming region. On the other hand, the oligoDNA gives marked fluorescence upon binding with the full-matched complement. The intensity of the fluorescent signal of the oligoDNA in a duplex changes depending on the position of the mismatched base of the complement.
