It is now tempting to correlate the decay coefficients, β, in CSS and OSS state. Figure shows the evolution of conductance as a function of n for p-acenes and m-acenes. It outlines an overall trend of decreasing conductance with increasing molecular length, which is indeed unchanged in both CSS and OSS state. However, the decay is much steeper in OSS state than that in CSS state, as can be inferred from decay constant values, i.e. β = 0.216 in CSS state, whereas it increases to 0.768 in OSS state for p-acenes. Similarly, m-acenes yield β = 0.312 in CSS state and 0.563 in OSS state. This implies that in OSS state, longer molecules lead to even higher resistance. On contrary, for cumulenes (Figure ), inverted attenuation factors are observed. In CSS state, an increase in conductance is observed from n = 4 to 24 with negative β value of 0.099. The origin of anti-ohmic behavior of cumulenes is rooted in to the frontier MOs (Figure in SI) which are delocalized over the complete molecular backbone providing an efficient conducting pathway. More importantly, the delocalization of MOs is further extended to the terminal connecting sites which facilitates strong electrodemolecule coupling. This is in contrast to polyacenes where orbital coefficients diminish quickly at the terminal benzene rings. The substantial weight of the conducting frontier MOs on the terminal contact sites together with decreasing HOMO-LUMO gap in cumulenes engender both the factors in Eq. 4 to favour an increase in conductance. However in OSS state, which is ground state for higher members, yields positive β values of 0.134 with regular decay of conductance. Overall, the conductance increases upto a maximum wherein the lower members of the series with CSS ground state persist in anti-ohmic regime, in contrast, the emergence of OSS ground state for the higher members, provokes a regular decay of conductance. This indicates that anti-ohmic behavior do exists for lower cumulenes with CSS ground state, however if a restricted wavefunction is wrongly imposed to higher cumulenes with OSS ground state, it results in incorrect prediction of empirically negative β values. A similar transformation from the length increasing conductance to normal decay of conductance was also oberved by Mandado et al. when BS-UKS-DFT was employed instead of RKS-DFT for a series of polymeric chains. Thus, indicting that the suggested positive correlation between diradical character and conductance is not as uni-equivocal.
