New fluorescent probes based on gallium(III) corrole complexes for the recognit...
Santos, Carla I.M.; Santiago, Ana M.; Araújo, Ana R.L.; Pinto, Sandra; Agostinho, Rafaela; Simão, Sónia; Azevedo, Tomás Pais de; Antunes, CatarinaIn this work, three fluorescent probes for detection of hydrogen sulfide (H2S) where prepared based on gallium (III) corrole complexes bearing nitro groups at beta-pyrrolic positions. Two of the compounds selected, the 3-nitro5,10,15- tris(pentafluorophenyl)corrolatogallium(III)(pyridine) (CGa-NO2) and the 3,17-dinitro-5,10,15-tris (pentafluorophenyl)corrolatogallium(III)(pyridine) (CGa-2NO2) present one and tw...
Biocompatible hybrids based on nanographene oxide covalently linked to glycolpo...
Santos, Carla I.M.; Gonçalves, Gil; Cicuéndez, Monica; Mariz, Inês; Silva, Virgília S.; Oliveira, Helena; Campos, Fábio; Vieira, Sandra I.The major limitation in the development of hybrids based on graphene oxide (GO) and porphyrins is their dispersibility and stability in aqueous systems due to the hydrophobic character induced by porphyrins. Most of the previous approaches reported the direct functionalization of GO with polyethylene glycol (PEG) chains followed by the self-assembly of porphyrins by π-π interactions. Here, new hybrids were prep...
