[Optical limiting cycling performance and photostability of vanadyl phthalocyanines and naphthalocyanines].
Optical limiting (OL) cycling performance and photostability of vanadyl phthalocyanines (VOPcs) and naphthalocyanines (VONcs) were studied. The results show that although vanadyl 2,11,20,29-tetra-tert-butyl-2,3-naphthalocyanine has the most pronounced OL effect originally, it is not a promising OL material due to its poor photostability. Meanwhile, vanadyl 2,9, 16,23-etraphenoxy-29H, 31H-phthalocyanine is considered to be a potential OL material, owing to its considerable OL effect and good photostability. A possible photochemical mechanism behind the reverse saturable absorption (RSA) and photolysis process of the studied species is proposed.
