Abstract

We report a low-temperature scanning tunneling microscopy investigation of the in-situ growth of gadolinium phthalocyaninato complexes by combined deposition of free-base phthalocyanines and gadolinium atoms on a smooth Ag(111) substrate. A careful control of the stoichiometry allows the expression of a multilevel structurecomposed of irregularly distributed Gd_x-1 (Pc)_x complexes, x=2-5, thus paving new avenues for surface-confined columnar growth.

Keywords: density functional calculations; lanthanides; multi-decker complexes; phthalocyanine; scanning probe microscopy; supramolecular architectures.
