Thin solid films, 06/2009, Volume: 517, Issue: 15Journal Article
Vapor deposition of perfluorinated phthalocyanines with bulky perfluorpropyl groups (F 64Pc) yielded intensely colored thin films (20–100 nm) despite the large molecular weight. In situ electrical conduction and optical transmission measurements revealed an almost negligible extent of intermolecular electronic coupling. Such quasi-independent character of molecules in solids was confirmed by detailed spectroscopic ellipsometry. The influence of the bulky peripheral groups on the packing in the films and on the electronic and optical properties of the films as well as potential applications of this class of strong electron acceptors are discussed.
