Azulene, a polar 10 π-electron nonbenzenoid aromatic unit composed of fused 5-and 7-membered sp2-carbon rings, is an attractive molecule for designing new materials supporting charge delocalization and transport at the nanoscale. This work highlights the synthesis and characterization of the first linear, π-conjugated terazulenic organometallic (n = 3, X = NC, R = H or CO2Et in Figure 1) platform with Cr0 termini. Specifically, the redox chemistry and spectroscopic signatures of the terazulenic molecular linker will be examined through comparison to biazulenic (n = 2, X = NC in Figure 1) molecular linkers. Characterization was addressed by a variety of spectroscopic and electrochemical methods, as well as computationally, using Density Functional Theory.
