 | Vardeny, Zeev Valentine | Ultrafast dynamics of excitons and solitons in disubstituted polyacetylene | We studied the ultrafast photoexcitation dynamics in disubstituted polyacetylene (DPA). We found two distinctively different relaxation channels for the photogenerated excitons; ionic and covalent pathways. In DPA films the photogenerated odd-parity (Bu) excitons that are responsible for the high ... | Ultrafast dynamics; Photoexcitation; Excitons; Disubstituted polyacetylene; Excitons; DPA; Relaxation channels | 2003-01 |
