No cyanine dyes are infrared, however there two types that are near-infrared:
Indole heptamethine cyanine dyes (known as Cy7): This class of cyanine dyes have the ability to generate strong fluorescence emission at the near-infrared (NIR) region of 650nm – 900 nm. It varies largely on the solvent and concentration of the solution.
Pyrrolopyrrole cyanine (PPCy) dyes: This class of cyanine dyes have the ability to generate strong fluorescence emission at the near-infrared (NIR) region of 684nm - 864 nm.
