Development of a Procedure for the Synthesis of Two-Dimensional Polymeric Phthalocyanines Under High Vacuum Conditions — •Pascal Schweitzer1,2, Clemens Geis1,2, and Derck Schlettwein1,2 — 1Justus-Liebig-University Giessen, Institute of Applied Physics — 2Justus-Liebig-University Giessen, Laboratory for Materials Science (LaMa)
As two-dimensional polymeric structures are of special interest in current research and phthalocyanine-based molecules can be used in various application fields the setup of a well-controlled synthesis route is needed. High vacuum conditions provide a well-defined reaction environment. A possible synthesis route to polymeric phthalocyanine sheets consists in the reaction of 1,2,4,5 tetracyanobenzene with a metal or metal salt. To achieve control over the reaction and, hence obtain optimized products, the understanding of the reactant behavior under high vacuum conditions is essential. Critical points that have to be considered are the sticking of the molecules on the substrate and the quartz microbalance during the PVD process, compound vapor pressure as well as side-reactions even during heating of the source.
