Singlet open-shell conjugated networks generated by singular graphs: Use of Huckel-like models
SSI Institute of Single Crystals, National Academy of Sciences of Ukraine, 60 Nauky Ave., 61001 Kharkiv, Ukraine
We show how the conventional tight-binding (TB), i. e., Huckel method can be consistently extended to open-shell singlet ground states of polyradical alternant systems that correspond to singular graphs. This leads us to the open-shell TB (OS-TB) model which is presented in detail and compared here with more complicated π-electron approximations. In particular, the earlier introduced quasi-correlated TB (QCTB) method and its extension (EQC) are involved into assessing the accuracy of OS-TB. It is shown that commonly used bond-order matrices, as well as electron-unpairing densities are described well by OS-TB, whereas π-electron Green functions generally are not. At the same time, we demonstrate that the related models, QCTB and EQC, provide reasonable estimates of molecular conductance (at the Fermi energy) in polyradical conjugated networks. The obtained results may be used for a design of active molecular elements in nanoelectronics.
