Charges soliton dynamics in trans-polyacetylene.
01 January 1986
Picosecond time-resolved absorption studies of the midgap absorption associated with photogenerated charged solitons in trans-polyacetylene are reported. Both direct photogeneration of charged soliton pairs and neutral to charged soliton conversion are observed. The former are created by intrachain absorption and annihilate on a subpicosecond timescale. The latter are formed following interchain photoexcitation and are the dominant population of charged solitons at times greater than 20 ps.
