Influence of meso-substituted tetraphenylporphyrin derivatives molecular structure on their supramolecular organization in bulk samples and fhin films

In order to study the influence of molecular structure features on their supramolecular organization in the bulk samples and thin films 10 new meso-substituted tetraphenylporphine derivatives and their metal complexes with substitution in para — or ortho-positions (-OC
