Abstract

Hybrid Er-Tetraphenylporphyrin (Er-TPP) thin films have been synthesized on a SiO(2)/Si(100) substrate in a co-deposition approach that combines an H(2)TPP seeded supersonic molecular beam and an effusive molecular beam of the metal. As confirmed by detailed surface electron spectroscopies, our experiments in ultrahigh vacuum demonstrate the ability to produce and control the chemical reactivity between the two species on the surface of the growing film. This is achieved by fully exploiting the unique features of the supersonic molecular-beam deposition approach in a co-deposition scheme that we show to be ideally suited to induce and control chemical reactivity. We believe that the ability to synthesize organolanthanides films, showing a thickness that is suitable for applications in optoelectronics, could pave the way to a class of devices based on active materials chemically engineered via this solid-state/vapor phase approach in vacuum.
