  "abstract": "Two-photon absorption (2PA) has emerged as a powerful strategy in photodynamic therapy (PDT), enabling deeper tissue penetration and spatially controlled photoactivation within the near-infrared (NIR) therapeutic window. Herein, we report the synthesis of a series of four porphyrin derivatives based on a meso-tetrafluorenylporphyrin core functionalized with four trans-chlorobis(dppe)ruthenium alkynyl units (dppe = 1,2-bis(diphenyl-phosphino)ethane) at the periphery. Their UV-vis (linear) and third-order nonlinear absorption properties were systematically investigated. In these multipolar assemblies, the incorporation of organoruthenium endgroups markedly enhances the two-photon absorption (2PA) cross-sections while efficiently quenching any light emission. As a result, remarkable photothermal molecules with strong nonlinear absorption in the near-IR range and also oxygen-photosensitizing properties are obtained. Despite their pronounced hydrophobicity, these organometallic photosensitizers can be effectively internalized in cellulo through encapsulation within polymeric nanoparticles (NPs) which allows anticancerous phototherapy with MCF-7 cell lines. Finally, the remarkable third-order nonlinear optical (NLO) properties of these outstanding two-photon absorbers, as well as their potential applications in various fields are briefly discussed.",
