Abstract

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 K c 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 G 0, indicating that the molecular framework possesses efficient charge transport capability.
