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…
Frenkel biexcitons in hybrid HJ photophysical aggregates
Elizabeth Gutiérrez Meza, Ravyn Malatesta, Hongmo Li +9
Frenkel excitons, the primary photoexcitations in organic semiconductors that are unequivocally responsible for the optical properties of this materials class, are predicted to for…
Microstructural control suppresses thermal activation of electron transport at room temperature in polymer transistors
Alessandro Luzio, Fritz Nubling, Jaime Martin +9
Recent demonstrations of inverted thermal activation of charge mobility in polymer field-effect transistors have excited the interest in transport regimes not limited by thermal ba…
Confinement Effects on the Crystalline Features of Poly(9,9-dioctylfluorene)
Jaime Martín, Alberto Scaccabarozzi, Aurora Nogales +3
Typical device architectures in polymer-based optoelectronic devices, such as field effect transistors organic light emitting diodes and photovoltaic cells include sub-100 nm semic…
New 3,3'-(ethane-1, 2-diylidene)bis(indolin-2-one) (EBI)-based small molecule semiconductors for organic solar cells
Mylene Le Borgne, Jesse Quinn, Jaime Martín +3
A series of donor-acceptor-donor (D-A-D) structured small-molecule compounds, with 3,3'-(ethane-1,2-diylidene)bis(indolin-2-one) (EBI) as a novel electron acceptor building block c…
Synthesis and properties of a novel narrow band gap oligomeric diketopyrrolopyrrole-based organic semiconductor
Mylene Le Borgnea, Jesse Quinn, Jaime Martín +3
An oligomeric semiconductor containing three bisthiophenediketopyrrolopyrole units (Tri-BTDPP) was synthesized and characterized. Tri-BTDPP has a HOMO level of -5.34 eV, a broad ab…
Solid-state-processing of d_PVDF
Jaime Martín, Dong Zhao, Thomas Lenz +3
Poly(vinylidene fluoride) (PVDF) has long been regarded as an ideal piezoelectric plastic because it exhibits a large piezoelectric response and a high thermal stability. However,…
Excitonic coupling dominates the homogeneous photoluminescence excitation linewidth in semicrystalline polymeric semiconductors
Pascal Grégoire, Eleonora Vella, Matthew Dyson +6
We measure the homogeneous excitation linewidth of regioregular poly(3-hexylthiophene), a model semicrystalline polymeric semiconductor, by means of two-dimensional coherent photol…
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…
Multi-phase semicrystalline microstructures drive exciton dissociation in neat plastic semiconductors
Francis Paquin, Jonathan Rivnay, Alberto Salleo +2
The optoelectronic properties of macromolecular semiconductors depend fundamentally on their solid-state microstructure. For example, the molecular-weight distribution influences p…
Two-dimensional spatial coherence of excitons in semicrystalline polymeric semiconductors: The effect of molecular weight
Francis Paquin, Hajime Yamagata, Nicholas J. Hestand +8
The electronic properties of macromolecular semiconductor thin films depend profoundly on their solid-state microstructure, which in turn is governed, among other things, by the pr…
Charge separation by photoexcitation in semicrystalline polymeric semiconductors: An intrinsic or extrinsic mechanism?
Francis Paquin, Gianluca Latini, Maciej Sakowicz +5
We probe charge photogeneration and subsequent recombination dynamics in neat regioregular poly(3-hexylthiophene) films over six decades in time by means of time-resolved photolumi…
Background-free quasi-steady-state photoinduced absorption spectroscopy by dual optical modulation
Houssem Kallel, Gianluca Latini, Francis Paquin +3
We present a simple and inexpensive means to measure background-free photoinduced absorption spectra by implementing a dual optical modulation scheme. Our objective is to measure q…
