The tetramers of azapentacene derivatives with unique hash mark (#)-shaped structures were prepared in a quite facile manner. The #-shaped tetramers are optically active due to possessing extended bia
Although understanding the conformations and arrangements of conjugated materials as solids is key to their prospective applications, predictive power over these structural factors remains elusive. In
Two coumarin/pyrrole-fused heterocycles were synthesized to investigate their photochemical and redox-switching properties. Photooxidation of the colorless diphenyl-substituted pyrrolocoumarin resulte
Herein we describe the structure–property relationships of three biazulene isomers (2,6′-biazulene (BAz1), 2,2′-biazulene (BAz2), and 6,6′-biazulene (BAz3)). The unimolecular planarities of these mole
Five rigid oxadiazole (OXD) containing silanes, denoted 1–5, have been developed with high morphological stability. Disruption of the π-aromatic conjugation by introduction of Si atoms leads to a larg
