| Outline of Final Research Achievements |
We developed surface-grafted polymer brushes containing liquid-crystalline semiconducting moieties in side chains aiming at precise control of nanostructures in organic devices. We synthesized semiconducting monomers containing perylene diimide (PDI), phthalocyanine and oligothiophene moieties. Among them, PDI monomers showed high reactivity for forming polymer brushes through surface-initiated atom transfer radical polymerization (SI-ATRP). The shape of the absorption spectrum of the polymer brush was similar to that of monomer, confirming the surface modification by PDI. Atomic force microscopy (AFM) images showed PDI domains with the widths in the order of ten nanometers. Furthermore, we prepared donor/acceptor heterostructures by spincoating poly(3-hexyl thiophene) (P3HT) on a PDI polymer brush film. It was confirmed that P3HT was successfully introduced into the PDI polymer brush film, thanks to the insolubility of surface-initiated polymer brushes.
