Abstract
Trends in thermal stability of aromatic macroheterocycles based of pheophorbide a and chlorin e6 containing hydrophilic groups have been revealed by means of thermogravimetric analysis at 298–1223 K under inert atmosphere. Methylpheophorbide a and 13(1)-N-methylamide of chlorin e6 are the most stable, the decomposition onset temperature being to 351 and 333°С. Their functional substitution leads to the reduction in thermal stability. Depending on the macrocycle structure the decrease in to can reach 20–200°С.
