The behavior of methylpheophorbide a in solution was studied by diffusion ordered NMR spectroscopy (DOSY), and its molecule association degree was estimated. It was found that methylpheophorbide a associates consist of an average of 4–5 molecules at room temperature. When the temperature increases the associate’s size decreases, and at 50–55 °C the associate’s size approaches to the size of the monomer.
