| Abstract: | The photodegradation kinetics of cyanine dyes and merocyanine dyes were studied by UV Vis absorption spectroscopy. The results show that the rate of the photofading reactions of the dyes follows quasi first order or zero order kinetics in acetonitrile. Those cyanine dyes holding a positive charge have relative good photostability comparing with merocyanines. |

| Keywords: | cyanine dyes photostability merocyanine dyes photodegradation |
