Abstract

Molecular orbital calculations with full geometry optimization using a semi-empirical tight-binding Hamiltonian for finite molecular models of phase kinks (solitons) in polyacetylene, (CH) X′ were done. This bond alternation defect extends over many atoms from which only ∼30 atoms are energetically important for stabilizing it. The neutral (spin-carying) phase kink is attracted by an energy on the meV scale to carbon atoms joining a non-hydrogen side-group, in contrast to charged phase kinks, where this attraction is estimated to be 100 to 1000 times larger.
