Two-Photon Absorption-Related Properties of Functionalized BODIPY Dyes in the Infrared Range up to Telecommunication Wavelengths

Aza boron-dipyrromethene dyes functionalized by extended donor-π-conjugated moieties present high potentialities for nonlinear applications in the telecommunication spectral range (1300–1500 nm). Their significant two-photon absorption cross-sections (σ2 > 600 GM) over this entire spectral range, combined with their high stability and solubility, allow nonlinear transmission experiments.
