With these ongoing trial and error debates on the feasibility of anti-ohmic wires, we undertook a theoretical investigation of length-dependence of the conductance in molecular wires exhibiting pronounced diradical character in their ground state. In the context of diradical character, the highly conjugated polyacenes, consisting of linearly fused benzene rings, have been widely debated in literature. Using unrestricted B3LYP calculations, Bendikov et al. established that smaller acenes (up to hexacene) have a closed-shell singlet (CSS) ground state, while higher acenes are predicted to be in open-shell singlet (OSS) ground state. This OSS state was found to be diradical in nature, consisting of two singly occupied molecular orbitals (SOMOs), each one localized on one of the two long edges with an anti-ferromagnetic coupling of unpaired electrons localized on the opposite edges. Afterwards, numerous experimental and theoretical reports aimed to validate the OSS ground state of higher order polyacenes. Employing a density matrix renormalization group (DMRG) algorithm by performing a full π-valence space CASSCF calculations, Chan et al. reached the same conclusion with OSS ground state for higher acenes (n >7). Followed by this, Jiang et al. also establised OSS ground state (n >7) based on spinpolarized generalized gradient approximation (GGA) calculations. However, the later two studies claimed that higher acenes (beyond n =12) are polyradical in nature, with more than one unpaired electrons accumulating on each of the edge. Indeed the corresponding natural orbital (NO) occupation numbers also turned out to be fractional, not only for the frontier highest occupied natural orbital (HONO) and lowest unoccupied natural orbital (LUNO), but also for the next nearest orbitals, i.e., HONO-1 and LUNO+1. Lately, particle-particle random-phase approximation (pp-RPA) calculations by Yang et al. gave the same qualitative answer, however, pushing the CSS to OSS crossover to larger acenes from n = 10 onwards. By means of Quantum Monte Carlo (QMC) methods, Dupuy et al. also found that the polyacenes exhibit a weak diradical character at least until n = 9. Using symmetry-broken DFT methods, Malrieu et al. demonstrated the evolution of OSS state from n =7 onwards, while the appearance of second spin symmetry breaking for n = 13 with four unpaired electrons centered at edges, thus presenting a simple picture compatible with the conclusions of best computations. In nutshell, different quantum chemistry methods used till date to understand the electronic structure of polyacenes have demonstrated different threshold length at which the CSS to OSS conversion takes place, however all of them agree to the same qualitative picture with open-shell diradical or polyradical character which increases progressively with the increasing length of polyacene series.
