Eight of three different kinds of long absorption wavelength dyes with typical structures have been chosen for studying the relation between structure and stability.The three kinds of dyes are quinocyanine.naphthothiacarbocyanine and carbocyanines.The environmental effect,such as light,oxygen and water,has been investigated.Results show that quinocyanine dyes prefer to hydrolytic reaction,while naphthothiacarbocyanine dyes tend to oxidizing reaction and photo-oxidation reaction process in singlet oxygen mechanism.
