“…Therefore, this class of compounds exhibits technological applications in different areas such as chemical sensors, 1−3 solar cells, 4−6 gas sensors, 7−9 liquid crystals, 10,11 optical data storage, 12,13 photodynamic therapy, 14−18 nonlinear optics, 19 and electrochemical applications such as electroctalytic, 20,21 electrosensing, 22,23 and electrochromic materials. 24 Although phthalocyanines display wide technological applications, because of the low solubility of phthalocyanines, their application is limited. To enhance the solubility, alkyl, alkoxy, phenoxy, methoxy, and macrocyclic groups can be attached to the peripheral positions of phthalocyanines.…”
