Ferrocene-anthracene-fused ladder-type molecules (2Fc-anti and 2Fc-syn) were achieved via a C-H activation/annulation strategy. This design extends the π-conjugated system through molecular ladderization, effectively elongating the molecular backbone and enhancing its delocalization. 2Fc-anti exhibits characteristic class II mixed-valence behavior, with superior equilibrium constant Kc compared to the non-ladderized control molecule 2Fc-nc. Single-molecule conductance measurements using the scanning tunneling microscopy break junction (STM-BJ) technique identified the most probable conductance of 10-3.3 G0, indicating that the molecular framework possesses efficient charge transport capability.

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...

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,...
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.
