| 摘 要： | 采用Z-扫描测试技术及UV/Vis吸收光谱研究钒氧酞菁(VOPcs)与萘酞菁(VONcs)的光限幅循环特性及光稳定性。结果表明，钒氧2,11,20,29-四取代叔丁基-2,3-萘酞菁最初表现出最好的光限幅效应，但光稳定性较差。钒氧2,9,16,23-四取代苯氧基-29H,31H-酞菁具有较强的光限幅效应和良好的光稳定性，是一种有应用前景的光限幅材料。探讨了VOPcs与VONcs的光解机理。

| Abstract: | 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. |
