dc.description.abstract | We report the spectroscopic changes of tetraphenylporphyrin carbon nanotube composites in a variety of
chlorinated solvents such as chloroform, dichloroethane and dichlorobenzene as a result of sonication.
Detailed data analysis suggests that protonation of the porphyrin core nitrogen atoms occurs as a result of
sonodegradation of the solvent molecules. Extreme care must be taken when working with carbon
nanotube composite solutions in chlorinated solvents, as sonication is always employed to disperse the
nanotubes. This finding is of enormous relevance to the materials chemistry community since these
solvents are widely used in preparation of carbon nanotube composite solutions. When working with
molecules that are capable of acting as a base some amount of protonation is inevitable and this may
dramatically change the physicochemical properties of the composite materials. | en |
