摘要
Two new contorted polycyclic aromatic hydrocarbons (PAHs) 1 and 2 were synthesized by acid-catalyzed benzannulation of a substituted anthracene. The isomers reveal dissimilar photophysical and redox properties with 2 having a much smaller HOMO-LUMO gap than 1. In the solid state, 2 packs in a unique two-dimensional herringbone motif that gives rise to efficient ambipolar charge transport in OFET devices, a feature not previously observed in contorted PAT-Is. On the other hand, 1 packs in one-dimensional dimerized pi-stacks and displays insulating properties.
