“…[13,14] Due to the extended π-system, wide coordination possibilities and the ability to form new covalent bonds due to peripheral substituents, phthalocyanines and their analogs can form hybrid systems with nanotubes, [15,16] fullerenes, [16] nanoparticles. [4,17,18] Compared to compositions in which the components do not form chemical bonds with each other, [19] hybrid materials have several advantages. For instance, in photovoltaics the use of hybrid materials can improve the efficiency of energy transfer [20] and accordingly reduce the thickness of the photoactive layer.…”
