Fluorinated phthalocyanines as molecular semiconductor thin films

Thin films of perfluorinated phthalocyanines F16PC show promise as molecular semiconductors in organic field effect transistors. A review is provided of growth studies and electrical characterization of presently discussed materials. Using this state-of-the-art as a starting point the synthesis and position of energy levels of partly fluorinated Zn(II) phthalocyanines is described. Growth characteristics of vapour-deposited thin films on inorganic and organic dielectrics are studied. Possibilities to use fluorinated phthalocyanines in technical applications of OFET are discussed.
