A number of conjugated molecules are designed with extremely long single C–C bonds beyond 2.0 Å. Some of the investigated molecules are based on analogues to the recently discovered molecule by Kubo et al. These bonds are analyzed by a variety of indices in addition to their equilibrium bond length including the Wiberg bond index, bond dissociation energy (BDE), and measures of diradicaloid character. All unrestricted DFT calculations indicate no diradical character supported by high-level multireference calculations. Finally,NFODwas computed through fractional orbital density (FOD) calculations and used to compare relative differences of diradicaloid character across twisted molecules without central C–C bonding and those with extremely elongated C–C bonds using a comparison with the C–C bond breaking in ethane. No example of direct C–C bonds beyond 2.4 Å are seen in the computational modeling; however, extremely stretched C–C bonds in the vicinity of 2.2 Å are predicted to be achievable with a BDE of 15–25 kcal mol–1.
