A method of increasing the multi-photon absorption cross-section of a porphyrin-based photosensitizer by attaching at least one TPA-chromophore at the meso- or beta-positions of a porphyrin structure of the porphyrin-based photosensitizer, and at least one intersystem crossing enhancing substituent to meso- or beta-positions of a porphyrin structure of the porphyrin-based photosensitizer, to thereby increase multi-photon absorption cross-section of the porphyrin-based photosensitizer to at least about 30 GM units at about its maximum wavelength for two-photon absorption. The TPA-chromophore is selected from a group of p-conjugated structures. The resulting porphyrin-based photosensitizer absorbs two photons of radiation in the range of about 700 nm to about 1300 nm. (Figure 2) discloses the molecular structures of three porphyrins.
