| Abstract: | As a kind of functional dyes,cyanine dyes have a wide application in the field of photo sensitizing material,CD,and others.Some cyanine dyes have a tendency of aggregation in solutions.The aggregates will have an important effect on their application capability.The UV Vis spectra in different conditions of a few important cyanines were investigated in this paper.We have found the effect of temperature and time on the behavior of aggregation.The solvent effect and the concentration effect were also studied. |

| Keywords: | cyanine dye J-aggregate UV-Vis spectra |
