Typically, the electronic dynamics in such systems are heavily dependant upon the aggregation state, and dynamics often occur on sub-nanosecond timescales.The authors thank the EPSRC for financial supportapplication/pdfen-AU© 2010 IEEEAggregation effectsAggregation stateElectronic dynamicsOrganic semiconductorPoly-thiopheneTime-scalesUltra-fastOptoelectronic devicesMicroelectronicsThe role of ultrafast torsional relaxation in the emission from polythiophene aggregates201010.1109/COMMAD.2010.56996892020-12-13
