The group studied a series of aza-BODIPY fluorophores with structures expected to have large two-photon cross-sections at telecommunication wavelengths. They found that it is possible to finely tune the linear and non-linear optical properties by chemical modification of the aza-BODIPY core and peripheral moieties, resulting in excellent, original candidates for nonlinear transmission and fluorescent labelling materials.
