2D acenes - heteroacenes - photostability

Significance

Large polycyclic aromatic hydrocarbons (PAHs) with high stability against air and water are highly sought after for the development of new organic electronics. Herein, the authors report two novel 2D bisthienoacenes that exhibit both impressive photostability and air stability. The incorporation of heteroatoms has also led to interesting photophysical properties.

Comment

Compounds 6a and 6b provide an interesting addition to the current library of PAHs. The most fascinating feature of these new 2D heteroacenes is the incorporation of a thiophene, which, in the case of 6a, has the potential for further functionalization through the α-positions of the annulated thiophenes. This feature transforms 6a into a potentially valuable building block in the development of new polymers with organic electronic applications.
