Monolayer properties of surface-active metalorganic complexes with a tunable headgroup

Surface-active metalorganic complexes can be used to construct organic thin films with excellent electronic and catalytic properties. We have recently introduced a new versatile surface-active ligand, which can efficiently coordinate a wide range of transition metals. In the present work we report an investigation of Langmuir monolayers of VV, MoVI and TiIV complexes of this ligand, using surface pressure–area isotherms, Brewster-angle microscopy, and Grazing incidence X-ray diffraction. The monolayers of these complexes are stable enough over broad temperature ranges to allow efficient transfer to solid substrates.
