Abstract:
Utilizing [14]dehydrobenzoannulene as an electron acceptor, four twisted donor-acceptor architectures were divergently synthesized. Intriguingly, the antiaromatic diazocine core could interrupt electron transfer in the π-frameworks. Benefiting from the junction of dehydrobenzoannulene and carbazoles, all displayed stunning fluorescence and electrochemiluminescence. Anomalously, blue-shifted fluorescence was observed in the electron-donating-group-substituted homologues. Finally, a molecular carbon-based sensor for dopamine detection was constructed. This work provides new insights into the construction and application of molecular carbons.

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the...
π Molecular Orbitals of 1,3-Butadiene
The simplest conjugated diene is 1,3-butadiene: a four-carbon system where each carbon is sp2-hybridized and has an unhybridized p orbital that contains an unpaired electron. According to molecular orbital theory, atomic orbitals combine to form molecular orbitals such that the...

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.

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is...
