摘要：Near-infrared dyes are becoming more and more important in modern technologies. To improve the stability and spectral properties, new heptamethine 3H-indocyanine dyes were synthesized and tested in solvents and SiO2 sol-gel. The results show that the dyes containing cyclohexenylene bridge and N-(4-carboxy) benzyl groups have better photostability and longer absorption wavelength than those containing linear heptamethine bridge and/or N-(5-carboxy)pentanyl groups. The absorption maxima are in reverse proportion to the polarity of the solvents. When dyes doped in SiO2 sol-gel, the absorption maxima are between their relative ones in methanol and in DMF.
