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.

Key words: cyanine dye, J-aggregate, UV-Vis spectra
