Description

Synthesis and characterization of covalently bound self-assembled, 5,10,15,20-Tetra(4-pyridyl)-21H,23H-porphine monolayer superlattices on various oxide surfaces such as fused silica, glass or silicon are described. The mono-molecular thin film structures are characterized by UV-visible ({lambda}{sub max} = 447 nm) and FTIR-ATR spectroscopy. In addition, X-ray photoelectron spectroscopy and secondary ion mass spectroscopy studies are used to confirm the formation of a self-assembled monolayer on the fused-silica surface. Attractive features in these complexes are their second-order nonlinear optical properties, enhanced by the completely delocalized {pi}-electrons. Second harmonic generation measurements have been used to determine the uniformity of the film, the relative and absolute … continued below

Attractive features in these complexes are their second-order nonlinear optical properties, enhanced by the completely delocalized {pi}-electrons. Second harmonic generation measurements have been used to determine the uniformity of the film, the relative and absolute magnitudes of nonzero elements of the nonlinear susceptibility, {chi}{sup (2)}, and the average molecular orientation of the chromophores.
