Description

Conjugated linear oligomers such as oligothiophenes, oligophenylenes, and oligofluorenes are typically synthesized and designed as wire-type functional materials. Meanwhile, we synthesized axially chiral 2,2'-methylenedioxy-bridged-1,1'-binaphthyl, quaternaphthalene, and octinaphthalene by bottom-up method from known binol. 2,2'-Methylenedioxy-bridges led to a continuous extremely cisoid conformation and subsequent extensive conjugation in the rod direction. Therefore, the absorption and fluorescence (in solution) region were red-shifted as the number of naphthalene rings increased. Moreover, the bridged oligonaphthalenes strongly fluoresced in the solid state under UV light.
