Metal phthalocyanines and porphyrins

Systematic studies of the role of such factors as the nature of the metal center and the detailed structure of the chelating ring, particularly its peripheral functionalization, can afford valuable information toward unveiling structure-activity relationships for macrocycles as electrocatalysts for oxygen reduction. The following sub-sections describe some of the most salient aspects of a selected number of transition metal phthalocyanines and porphyrins, including the effects of redox and non-redox active substituents on the properties of Co porphyrins.

Conducting Polymer Nanocomposites with Metal Phthalocyanines and Porphyrins... 

Generally, incorporating metal-phthalocyanines and porphyrins into CP matrix will decrease the conductivities of CPs [103]. However, such composites will show some enhanced chemical or physical properties such as sensing for vapors in comparison with the CPs alone which arises from their unique, specific properties such as semiconductivity, well-defined redox activity and high thermal stability [104,105]. It is well known that...
