The molecular structure of azulene, a polar nonbenzenoid aromatic hydrocarbon, involves an edge-sharing combination of 5- and 7-membered sp<sup>2</sup>-carbon rings. Linear biazulenes exhibit π-conjugation along their molecular axes and are attractive building blocks for designing materials relevant to applications in molecular and optoelectronics. In this presentation, the syntheses as well as structural, spectroscopic, and redox properties of 2-isocyano-6,6’-biazulene and 2-isocyano-6,2’-biazulene ligands and their electron-rich complexes will be discussed. In addition, the chemistry of the 2,2’’-diisocyano-6,2’-6’,6’’-terazulenic π-linker, which may be considered a “hybrid” of the above two linear isocyanobiazulenes, will be highlighted. Synthetic strategies for regioselective derivatization of the isocyanobiazulenic and diisocyanoterazulenic platforms to exert steric and electronic tuning thereof will be presented.
