Twisted carotenoids do not support efficient intramolecular singlet fission in the orange carotenoid protein
George A. Sutherland, James P. Pidgeon, Harrison Ka Hin Lee +8
Singlet exciton fission is the spin-allowed generation of two triplet electronic excited states from a singlet state. Intramolecular singlet fission has been suggested to occur on…
Band-edge Excitation of Carotenoids Removes S* Revealing Triplet-pair Contributions to the S1 Absorption Spectrum
Daniel W Polak, Andrew J Musser, George A Sutherland +7
The nature of the low-lying electronic states in carotenoids has been debated for decades. We use excitation-dependent transient absorption spectroscopy and comparison with publish…
Determining exciton bandwidth and film microstructure in polythiophene films using linear absorption spectroscopy
Jenny Clark, Jui-Fen Chang, Frank C. Spano +2
We analyze the linear absorption spectrum of regioregular poly(3-hexylthiophene) films spun from a variety of solvents to probe directly the film microstructure and how it depends…
The role of intermolecular coupling in the photophysics of disordered organic semiconductors: Aggregate emission in regioregular polythiophene
Jenny Clark, Carlos Silva, Richard H. Friend +1
We address the role of excitonic coulping on the nature of photoexcitations in the conjugated polymer regioregular poly(3-hexylthiophene). By means of temperature-dependent absorpt…
