All‐benzenoid Polycyclic Aromatic Hydrocarbons: Synthesis, Self‐assembly and Applications in Organic Electronics

A sequential cyclization/π-extension strategy for modular construction of nanographenes enabled by stannole cycloadditions

“…4 In general, the utility of these compounds stems from the diverse array of properties that can be synthetically controlled by tuning (for example) molecular shape, edge structure, and functionality. 5,6 Despite established advances in PAH chemistry, there remain substantial synthetic limitations that restrict possible architectures and new applications.…”

“…4,5 Moreover, the electronic properties of PAHs are intimately related to their structure; therefore small modications in their scaffold can lead to vastly different optical and electronic properties. [6][7][8][9][10][11][12][13][14] Truxene is a C 3 -symmetric PAH that has been intensively studied for the past 15-20 years. 15 In particular, it has been used as a precursor to polyarenes, 16,17 liquid crystals 18,19 and hemifullerenes, 20,21 all of which have potential to be used in organic electronics.…”
