PORPHYRIN-BASED SUPRAMOLECULAR NANOTUBES GENERATED BY AGGREGATION PROCESSES
Porphyrins can form a variety of structures from linear head-to-tail or J-aggregates to fractal aggregates with different and specific photophysical properties. In this paper, the controlled aggregation of meso-5 ,10, 15, 20-sulfonato-phenyl porphyrin (H2TPPS44-) was studied at room temperature. Structure of the aggregates was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and UV-visible spectroscopy.
