single molecule study of ClAlPc on Au(111) Surface with low temperature scanning tunneling microscopy — •Hao Zhu, Wenhui Zhao, Huanjun Song, and Kai Wu — CCME, Peking University, No.5 Yiheyuan Road Haidian District, Beijing, 100871

Chloroaluminum phthalocyanine(ClAlPc), a non-planar molecule with a Cl atom outside of the phthalocyanine plane, presented constant dipole moment. The adsorption behavior of ClAlPc single molecule deposited on Au(111) surface was studied with the technique of STM, STS and dI/dV mapping. ClAlPc adsorbed on Au (111) with three type of conformation, including Cl atom pointing towards the vacuum (U1 and U2) and Cl atom pointing towards the substrate. Different adsorption orientations were observed between the two types of molecules. Moreover, we measured the orbital states of each type of molecules using STS at the center and dI/dV mapping at various sample bias.
