A large part of this research paralleled the studies of porphyrins, which are well known for their biological relevance. Both phthalocyanines and porphyrins are appealing from the point of view of materials chemistry. Their metal complexes were studied as catalysts, small molecule transporters, electrical conductors, magnetic switches, etc.
Among many types of molecules investigated for molecular electronics applications, phthalocyanines are of particular interest because they are robust and capable of self-assembly, an important feature for technical processing purposes. In addition, their electronic properties can be tuned by substitution on the periphery of the macrocycle or introduction of a metal ion into its interior.
This thesis concentrates on phthalocyanine (Pc) derivatives that contain peripheral redox-active units, namely, tetrathiafulvalene (TTF). The latter is an excellent electron donor and a ubiquitous component of synthetic organic conductors. By introducing TTF at the periphery of the Pc macrocycle, we expect to achieve higher electronic delocalization and, consequently, improved transport properties of the resulting materials. We focus on modification of two classic one-dimensional conductors, CuPc and PbPc, and carry out a detailed investigation of their properties after the introduction of TTF units into the structure of these complexes.
