Abstract:
A novel dicyanofulvene dimer fused to a benzene ring (3a) has been synthesized as an electron-accepting molecule. The low-lying LUMO level was validated by measuring the ultraviolet photoelectron spectroscopy and electronic spectra. Cyclic voltammetry exhibited sequential reversible waves from 3a to 3a(4-) in a range of -0.30 to -2.14 V (vs Fc/Fc(+)). The electronic structure of 3a and its anionic species (3a(•-), 3a(2-), 3a(3•-), and 3a(4-)) were investigated by electronic spectra and X-ray crystallographic analyses.

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...

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...
