Abstract 15 Novel meso-substituted tetraphenylporphyrins (TPP) and their metal complexes with substitution by alkoxygroups (-OC4H9 and -OC16H33) in para- or ortho-positions were studied. The influence of molecular structure of porphyrins on their supramolecular organization both in the bulky samples and in thin films were investigated by the thermal polarizing and atomic-force microscopies. Optical properties of thin films derived by the Langmuir-Schaefer method were studied.
