Energy Transfer from Fluorene Based Conjugated Polyelectrolytes to Onchain and ...
Marques, Ana T.; Pinto, Sara M. A.; Monteiro, Carlos J. P.; Melo, J. Sérgio Seixas de; Burrows, Hugh D.; Scherf, Ullrich; Calvete, Mário J. F.A new water soluble fluorene-based polyelectrolyte containing on-chain porphyrin units has been synthesized via Suzuki coupling, for use in optoelectronic devices. The material consist of a random copolymer of poly{1,4-phenylene-[9,9-bis(4-phenoxy butylsulfonate)]fluorene-2,7-diyl} (PBS-PFP) and a 5,15-diphenylporphyrin (DPP). The energy transfer process between the PBS-PFP units and the porphyrin has been inve...
Synthesis of amphiphilic sulfonamide halogenated porphyrins: MALDI-TOFMS charac...
Monteiro, Carlos J. P.; Pereira, Mariette M.; Pinto, Sara M. A.; Simões, Ana V. C.; Sá, Gonçalo F. F.; Arnaut, Luís G.; Formosinho, Sebastião J.Porphyrins are key precursors for development of photosensitizers for photodynamic therapy. A new series of ortho-halogenated tetraarylporphyrins with sulfonamide substituents have been synthesized via chlorosulfonation reaction and characterized by MALDI-TOFMS. To predict their partition properties, log KOW of a selected range of the synthesized halogenated amphiphilic porphyrins is described. A significant ef...
