Synthesis Langmuir-Blodgett technique

Adding substituents on the phthalocyanines macrocycles of the sandwidi complexes is not only the way to modify the electronic properties, but is also usefiil for increasing the solubility of these com[dexes. The synthesis of unsymmetrical mdecules is also important for orientation of the molecules for building films by the Langmuir-Blodgett technique. But the aim of the present work is to study the modification of the electronic structure induced by the asymmetry of die molecule.
