    We have investigated the initial stage of adsorption of a conjugated aromatic compound, 1,4-bis[β-pyridyl-(2)-vinyl]benzene (P2VB), on the clean Si(100)-2 × 1 surface. Using scanning tunneling microscopy (STM), we observed four different adsorption directions. An individual molecule appears as two or three bright spots, the brightness and distance between bright spots varying for different adsorption directions. We conclude that STM revealed the electronic states of the Si(100) dimers modulated by the adsorbed molecules, rather than the molecules themselves. Initial stage of adsorption of this molecule is explained by considering the molecular size and shape and strong interaction between the molecule and the Si dimers.
