TLDR
CW photomodulation technique has been applied to study the photoexcitations of both a form of soluble polyacetylene with controlled conjugation length and an unsymmetrical polydiace-tylene and its oligomers.Abstract:
Purpose of this research has been to investigate the dependence of the non linear excitations in conjugated polymers on their conjugation length. To this end CW photomodulation technique has been applied to study the photoexcitations of both a form of soluble polyacetylene with controlled conjugation length and an unsymmetrical polydiace-tylene and its oligomers.read more

Chain-end effects in Su-Schrieffer-Heeger-type models of alternating trans-polyacetylene
TL;DR: In this paper, the ansatz for the potential due to σ-electron is reformulated so that no additional linear terms to avoid chain shrinking are necessary, and the second-neighbour resonance integrals of a magnitude suggested by experimental findings are shown to have no influence on soliton dynamics.
