1,4-Dithienyl-2,5-divinylbenzenes are readily available compounds that undergo oxidative photocyclization to afford bent anthradithiophenes (BADTs). The new parent and didodecyl-functionalized derivatives have been structurally characterized, and their absorption and emission spectra are reported.
Evaluation of semiconducting molecular thin films solution-processed via the photoprecursor approach: the case of hexyl-substituted thienoanthracenes
The photoprecursor approach is superior to direct spin coating in preparing high quality organic semiconducting thin films.

slipping along their long and short molecular axes while the diphenyl derivative packs into an edge-to-face herringbone arrangement. Powder diffraction data show that in thin films prepared by vacuum evaporation, molecules of the unsubstituted BADT are oriented nearly perpendicular to the substrate surface whereas the dialkylated derivatives adopt either multiple phases or new polymorphs.
