The Nature of the Phase Transition Observed for Monolayers of Azulene on Pt(III).

Abstract

A model is presented for the reversible phase transition observed for azulene monolayers on Pt(III). Below the transition temperature the overlayer LEED pattern consists of (3x3) aligned with the substrate and (3x3) rotated by 30 degrees. Above the transition temperature the LEED pattern is a (3x3) aligned with the substrate. The model attributes the phase transition to an order-disorder transition of the rotational orientation of azulene molecules with the molecular plane parallel to the surface. (Author)
