“…[78a] Inspired by this,M azzier et al developed polypeptide polymers that were end-capped with C 60 by using at hermally Figure 8. [80] Ther esulting polymers were found to self-assemble in water into rodlike microstructures that had C 60 on either their NorCterminus.T he goal of this work was to impart photophysical and/or electrochemical functionalities to polypeptide microstructures,a sw ell as to outline ar oute for the large-scale production of fullerenebased devices.U ltimately,t his study demonstrated that, by taking advantage of the ease and simplicity of thiol-ene reactions,t he possibility of imparting such functionalities is indeed possible.

Although well-known and studied for centuries, sulfur continues to be at the center of an extensive array of scientific research topics. As one of the most abundant elements in the Universe, a major by-product of oil refinery processes, and as a common reaction site within biological systems, research involving sulfur is both broad in scope and incredibly important to our daily lives. Indeed, there has been renewed interest in sulfur-based reactions in just the past ten years. Sulfur research spans the spectrum of topics within the physical sciences including research on improving energy efficiency, environmentally friendly uses for oil refinery waste products, development of polymers with unique optical and mechanical properties, and materials produced for biological applications. This Review focuses on some of the latest exciting ways in which sulfur and sulfur-based reactions are being utilized to produce materials for application in energy, environmental, and other practical areas.

“…Daran anknüpfend entwickelten Mazzier et al. Polypeptidpolymere, die durch Anwendung thermisch initiierter Thiol‐En‐Reaktionen an den Enden mit C 60 verkappt wurden . Es wurde gefunden, dass die gebildeten Polymere in Wasser durch Selbstorganisation zu stäbchenförmigen Mikrostrukturen aggregierten, an deren N‐Terminus oder C‐Terminus C 60 gebunden war.…”

Schwefel ist eines der häufigsten Elemente im Universum, fällt als Hauptnebenprodukt bei der Erdölraffination an und stellt ein häufiges Reaktionszentrum in biologischen Systemen dar. Die Forschung über Schwefel ist daher breit gefächert und hat große Relevanz und Auswirkungen auf unser tägliches Leben. So hat das Interesse an schwefelbasierten Reaktionen in den letzten zehn Jahren eine deutliche Wiederbelebung erfahren. Weitere relevante Themengebiete sind Forschungen zur Verbesserung von Energieeffizienzen, umweltfreundliche Anwendungen für Abfallprodukte der Erdölraffination, Polymere mit besonderen optischen und mechanischen Eigenschaften sowie Materialien für biologische Anwendungen. Dieser Aufsatz stellt einige der neuesten Anwendungen von Schwefel und schwefelbasierten Reaktionen für die Herstellung von Materialien für den Energiebereich, Umweltschutz und andere praktische Anwendungen vor.

“…A well‐defined self‐assembly of the π‐conjugated molecule directly influences the performance of devices . In the past few years, C 60 and its derivatives have been widely used as an important fundamental unit to construct the supramolecular architectures, which are useful in optoelectronic devices . The properties of self‐organized C 60 derivatives are more attractive due to the formation of nano‐structured assembly, which decides the performance of the devices made up of it.…”

Self-assembly of fullerene derivatives plays an important role in controlling photovoltaic performance of organic solar cells (OSCs). Herein, we have synthesized two covalently bonded phenyl substituted fullerene derivatives -N-Mtheyl-2-[2,5-bis (trifluoromethyl)phenyl] fullerenopyrrolidine (1) and N-Methyl-2-[2,4bis(trifluoro-methyl-6-methoxy)phenyl]fullerenopyrrolidine (2), which are employed as electron acceptors in OSCs. The self-assembly of two aforementioned molecules were investigated in the binary solvent system of chloroform and methanol (1:1 volume ratio). Further, optical, electro-chemical and micro-structural properties of self assembled structures were also studied. It is found that the architecture of assembly is directed by the functional groupsatthe phenyl ring and solvent molecule. The molecule 1 possessing -CF3 group and the molecule 2 possessing additional -OMe group on fullerene unitform flowers and flakes like structures, respectively. The assembly structure of 1 gets converted from flower to disc like structure with the variation of solvent from methanol to hexane. The OSCs fabricated using molecule 1 and molecule 2 as acceptor with PTB7 donor showed a power conversion efficiency of 6.8 and 3.6%, respectively with high open circuit voltages of ∼ 0.8 V.
