  The reaction dynamics of the Bi-line structure (BLS) with copper-phthalocyanine (CuPc) molecules have been investigated by scanning tunneling microscopy. Bi atoms deposited on the Si(100) surface at 400-500°C, form one-dimensional wires consisting of two chains of Bi dimers in the topmost layer. When CuPc molecules were deposited on the Si(100) surface with the BLSs at room temperature, we observed bright 4-spot shapes and c(4×4) structures in the terraces. When the surface was annealed at 200°C, the bright 4-spot disappeared and the area with c(4×4) periodicity increased. The CuPc molecules, adsorbed on BLSs, were dissociated by catalytic reaction of Bi atoms.<br>
