Water-soluble self-assembled butadiyne-bridged bisporphyrin: a potential two-photon-absorbing photosensitizer for photodynamic therapy.
We have synthesized a novel, two-photon-absorbing photosensitizer for two-photon-absorption photodynamic therapy (2PA-PDT). The molecule is a butadiyne-bridged porphyrin dimer terminated with two water-soluble porphyrin monomers connected through Zn-imidazolyl self-assembly and covalently linked through olefin metathesis. It has an effective two-photon-absorption (2PA) cross-section value, sigm...
متن کاملOrganic Nanomaterials with Two-Photon Absorption Properties for Biomedical Applications
During recent years there have been notorious advances in the development of organic molecules and π-conjugated polymers with two-photon activity, i.e., emission of fluorescence promoted by the molecular absorption of two photons. Novel organic materials have reached very large two-photon activity, and many of them have been processed successfully into nanostructured platforms. In contrast to t...
متن کاملTwo-Photon Absorbing Molecules as Potential Materials for 3D Optical Memory
In this review, recent advances in two-photon absorbing photochromic molecules, as potential materials for 3D optical memory, are presented. The investigations introduced in this review indicate that 3D data storage processing at the molecular level is possible. As 3D memory using two-photon absorption allows advantages over existing systems, the use of two-photon absorbing photochromic molecul...
متن کاملPhotosensitizer-doped conjugated polymer nanoparticles for simultaneous two-photon imaging and two-photon photodynamic therapy in living cells.
Photosensitizer doped conjugated polymer nanoparticles have been prepared by incorporating polyoxyethylene nonylphenylether (CO-520) into the nanoparticles using a re-precipitation method. The conjugated polymer, poly[9,9-dibromohexylfluorene-2,7-ylenethylene-alt-1,4-(2,5-dimethoxy)phenylene] (PFEMO), was used as the host matrix to disperse tetraphenylporphyrin (TPP) and an energy donor to enha...
متن کاملDevelopment of Novel Two- Photon Absorbing Chromophores
There has been much interest in the development of two-photon absorbing materials and many efforts to understand the nonlinear absorption properties of these dyes but this area is still not well understood. A computational model has been developed in our lab to understand the nanosecond nonlinear absorption properties that incorporate all of the measured one-photon photophysical parameters of a...
