Dialkoxybenzo[ j ]fluoranthenes: synthesis, structures, photophysical properties, and optical waveguide application

A series of dialkoxybenzo[j]fluoranthene derivatives were readily and efficiently synthesized in gram scale starting from the commercial 6- or 7-methoxy-1-tetralone. The crystal structures of the BjF derivatives were described, and their structure–optical properties in solution and in the solid state were investigated. Moreover, this kind of organic material also exhibited excellent optical waveguide behavior owing to their large Stokes shifts and high crystallinity.
