Three dithienobenzimidazole derivative monomers (M1, M2, and M3) were prepared, where M3 was obtained by the oxidation of M1 and identified by the X-ray crystallographic analysis. pi-Conjugated homopolymers (P1-0, P2-0, and P3-0) and copolymers (P...
Bidentate organic molecules with imidazole or benzimidazole moieties connected to a rigid 1,3-diphenyladamantane spacer are simple and unique building blocks that facilitate the assembly of supramolecular architectures in the solid state via metal...
