Abstract: The molecular morphology of CuTPP has been investigated through depositing onHOPG using Langmuir- Blodgett technique. High resolution STM images showed that theCuTPP molecules presented plane cyclic shape of diameter l.0nm, without strand and helixstructure. The result is very close to the ideal structure of a CuTPP molecule. The condi-tions of STM imaging of CuTPP molecules have been discussed.
