Abstract: This article presents a study, which focuses on strong two-photon absorption (2PA) in &pie;-conjugated porphyrin dimers via double-resonance enhancement in a three-level model. Applications of 2PA, such as high-resolution 3D microscopy, deep tissue-penetrating photodynamic therapy, 3D micro- and nanofabrication, high-density optical data storage, and optical power limiting, depend critically on the availability of materials with high 2PA cross sections and on the ability of these chromophores to perform specialized photophysical, photochemical, or photobiological functions.
