Abstract:
Dinaphthothiophene has been reported as a promising p-type semiconductor. The development of high-performance n-type semiconductors is highly desirable. The introduction of an imide group into polycyclic aromatic hydrocarbons can lower their LUMO levels to meet the basic requirement of n-type organic semiconductor materials. In this work, we have synthesized four imide-modified dinaphthothiophenes and dinaphthothiophenedioxides. Their optoelectronic properties have been investigated. Their low-lying LUMO levels make them potential n-type semiconductor candidates.

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 double...

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 more stable,...
