Selenolate is considered as an alternative to thiolate serve a headgroup mediating the formation of self-assembled monolayers (SAMs) on coinage metal substrates. There are, however, ongoing vivid discussions regarding advantages and disadvantages these anchor groups, regarding, in particular, energetics headgroup–substrate interface their efficiency terms charge transport/transfer. Here we introduce well-defined model system 6-cyanonaphthalene-2-thiolate -selenolate SAMs Au(111) resolve...
The surface properties of polymeric biomaterials play a crucial role in their biocompatibility and performance. This study explores the application cold oxygen plasma treatment as versatile technique for modification materials with different degrees crystallinity: crystalline high-density polyethylene (HDPE), crystalline-amorphous poly(chloro‑paraxylylene) (parylene C), amorphous aromatic polyether-based polyurethane (PU). investigations focus on generation functional groups hydrophilicity,...
Blends of the low-bandgap polymer poly[(9,9-dioctylfluorenyl-2,7-diyl)-co-5,5- (4',7'-di-2-thienyl-2',1',3'-benzothiadiazole] (APFO-3) and fullerene derivative [6,6]-phenyl–C61–butyric acid methyl ester (PCBM) were spin-coated from chloroform solution into thin films, which examined with dynamic secondary ion mass spectrometry. For blends high PCBM content, depth profiles show composition waves that caused by surface-directed phase separation during spin-coating. The formation such...
