Studies on the Wettability of Molecular Deposition (MD) Films of Phthalocyanine Copper Cation and Anion on Quartz Substrate

Abstract

Abstract: The result of UV-Vis adsorbance indicates that phthalocyanine copper cation and anion monolayers are alternately deposited, and dimmer is the major form. Through analyzing the 20th phthalocyanine MD film AFM image, we know that the surface of MD film is flat and compact. The physical-chemical properties of molecular end-group have influence on the MD films surface character notably. The contact angles of water on the odd and even layer MD films vary greatly complying with "odd-even" regularity, and the value increases slightly with the increment of MD film layers due to the decrease of van der Waals force reinforced by substrate through MD films.

Key words: Copper phthalocyanine tetrasulfonic acid tetrasodium salt(CuTsPc), Alcian Blue, Molecular deposition (MD) film, Wettability
