By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Biological Factors. According to news reporting out of Strasbourg, France, by NewsRx editors, research stated, "Herein the synthesis, characterization, and organization of a first-generation dendritic fulleropyrrolidine bearing two pending porphyrins are reported. Both the dendron and the fullerene derivatives were synthesized by Cu-I-catalyzed alkyne-azide cycloaddition (CuAAC)."
Our news journalists obtained a quote from the research from the University of Strasbourg, "The electron-donor-acceptor conjugate possesses a shape that allows the formation of supramolecular complexes by encapsulation of C-60 within the jaws of the two porphyrins of another molecule. The interactions between the two photoactive units (i.e., C-60 and Zn-porphyrin) were confirmed by cyclic voltammetry as well as by steady-state and time-resolved spectroscopy. For example, a shift of about 85mV was found for the first reduction of C-60 in the electron-donor-acceptor conjugate compared with the parent molecules, which indicates that C-60 is included in the jaws of the porphyrin. The fulleropyrrolidine compound exhibits a rich polymorphism, which was corroborated by AFM and SEM. In particular, it was found to form supramolecular fibrils when deposited on substrates."
According to the news editors, the research concluded: "The morphology of the fibrils suggests that they are formed by several rows of fullerene-porphyrin complexes."
