title = "The effect of branching on the one- and two-photon absorption, cell viability and localization of cationic triarylborane chromophores with dipolar vs. octupolar charge distributions for cellular imaging",
abstract = "Two different chromophores, namely a dipolar and an octupolar system, were prepared and their linear and non-linear optical properties as well as their bioimaging capabilities were compared. Both contain triphenylamine as the donor and a triarylborane as the acceptor, the latter modified with cationic trimethylammonio groups to provide solubility in aqueous media. The octupolar system exhibits a much higher two-photon brightness, and also better cell viability and enhanced selectivity for lysosomes compared with the dipolar chromophore. Furthermore, both dyes were applied in two-photon excited fluorescence (TPEF) live-cell imaging.",
