Topological nature of intrinsic structural defects in a trans-polyacetylene chain

  • 27 Accesses


Using a topological approach, we consider the nature of intrinsic structural defects in a real trans-polyacetylene chain. We show that remnant cis segments are internal diaclination loops having two components: a wedge loop of strength ±π/3 and a twist loop of strength π, while defects of the soliton type are a combination of a point dislocation and an external twist disclination loop of strength π.
