Formation of a highly ordered red phase in a MEH-PPV: polystyrene pseudogels
Elham Rezasoltani, Jaime Martin, Sophia C. Hayes +5
In this work, we demonstrate the formation of a "red-phase" poly[2-methoxy, 5-(2'- ethyl-hexoxy)-1,4-phenylene vinylene-PPV] (MEH-PPV) embedded into a host matrix of highly entangl…
Direct observation of ultrafast long-range charge separation at polymer:fullerene heterojunctions
Françoise Provencher, Nicolas Bérubé, Anthony W. Parker +7
In polymeric semiconductors, charge carriers are polarons, which means that the excess charge deforms the molecular structure of the polymer chain that hosts it. This effect result…
Investigation of the Solvent-Dependent Photoluminescence Lineshapes in 2,2'-Bithienyl-Substituted 4H-1,2,6- Thiadiazin-4-one
Soulianna Kasiouli, Eleni Theodorou, Christalla Kyriakou +4
The solvent dependence of 3,5-bis[(2,2'-bithien)-5-yl]-4H-1,2,6-thiadiazin-4-one BBT is investigated via absorption and photoluminescence spectroscopies. Large differences are obse…
Analysis of the excited-state absorption spectral bandshape of oligofluorenes
Sophia C. Hayes, Carlos Silva
We present ultrafast transient absorption spectra of two oligofluorene derivatives in dilute solution. These spectra display clear vibronic structure, which we analyze rigorously u…
Charge-transfer excitons in strongly coupled organic semiconductors
Jean-Francois Glowe, Mathieu Perrin, David Beljonne +3
Time-resolved and temperature-dependent photoluminescence measurements on one-dimensional sexithiophene lattices reveal intrinsic branching of photoexcitations to two distinct spec…
