Alternating copper phthalocyanine (CuPc) and di-indenoperylene (DIP) molecular chain arrays have been fabricated via nanoscale phase separation of this CuPc:DIP binary molecular system on Ag(111). In situ low-temperature scanning tunneling microscopy has been used to investigate the molecular self-assembling processes on surface and the structural property of the well-ordered nanostructure arrays. The results show that the formation of these supramolecular structures is governed by the noncovalent molecule-molecule interactions.
