Energy spectra and electric and magnetic properties of 1D stacks of conjugated π-electron systems with defect surface states. I. π systems with tamm surface states

The energy spectra and the electric and magnetic properties of one-dimensional (1D) stacks consisting of conjugated π-electron systems (polycyclic aromatic hydrocarbons and polymethines) with Tamm defects are investigated theoretically by means of the many-electron band theory. The conditions for the relative arrangement of the stacks in terms of the slip parameters for yielding different magnetic and electric ground-state properties are studied.
