文摘

Four asymmetric bis-branched triphenylamine derivatives were easily synthesized. The branched triphenylmines possessed large two-photon cross-sections and low biotoxicity. The intramolecular charge transfer from one branch to another plays an important role. The branched triphenylamines were successfully applied in one- and two-photon fluorescence bio-imaging.
