[摘要]：Aza boron-dipyrromethene dyes functionalized by extended donor-pi-conjugated moieties show great potential for non-linear applications in the telecommunications spectral range (1300-1500 nm). Their significant two-photon absorption cross-sections (sigma(2)>600 GM) over this entire spectral range, combined with their high stability and solubility, allow non-linear transmission experiments.
