Chemisorption and Thermal Chemistry of Azulene and Naphthalene Adsorbed on Pt(III).

Abstract

The ordering phenomena and thermal chemistry of the isomeric aromatic hydrocarbons azulene and naphthalene have been studied on a Pt(III) surface. Complete dehydrogenation with an onset of about 200 C is the eventual fate of these molecules absorbed on Pt(III). Several ordered phases exist for azulene overlayers as a function of coverage. Azulene overlayers with C/Pt atom ratios in the range 1-1.3 exhibit a reversible transition with temperature. The orientational ordering of neighboring molecules appears to be governed by intermolecular forces rather than the molecule-Pt interaction in both azulene and naphthalene overlayers. (Author)
