Abstract:
We report a para-quinodimethane skeleton (p-QDM)-based polycyclic aromatic hydrocarbon (PAH) with heptenes as end-capping groups and F-substituents in the central six-membered ring. This compound shows the syn-configuration in one crystal form with relative strong emission (ΦF = 0.25), and the anti-configuration in another crystal form with weak emission. Furthermore, this compound was transformed into the more annulated PAHs via on-surface C-F bond activations.

Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.

Stability of Conjugated Dienes
A comparison of the enthalpies of hydrogenation of dienes reveals that conjugated dienes release less heat on hydrogenation, rendering them more stable than their nonconjugated analogs.
