Journal ArticleDOI

Determination of the Internal Morphology of Nanostructures Patterned by Directed Self Assembly

TL;DR: A new measurement technique, resonant critical-dimension small-angle X-ray scattering (res-CDSAXS), is developed, to evaluate the 3D buried features inside the film and enable a better understanding of the fundamental physics behind the formation of buried features in DSA BCP films.
Journal ArticleDOI

High performance airbrushed organic thin film transistors

TL;DR: In this paper, spray-deposited poly-3-hexylthiophene (P3HT) transistors were characterized using electrical and structural methods, and they exhibited a saturation regime mobility as high as 0.1 cm2/V−1/s−1, which is comparable to the best mobilities observed in high molecular mass P3HT transistors prepared using other methods.
Journal ArticleDOI

Readily Accessible Benzo[d]thiazole Polymers for Nonfullerene Solar Cells with >16% Efficiency and Potential Pitfalls

TL;DR: In this paper, the authors report facile, high-yield synthetic access to the difluoro BTA building block, 4,7-bis(5-bromo-4-(2-hexyl-decyl)-thiophen-2-yl)-5,6-difluor-2-(pentadecan-7-yl)benzo[d]thiazole (BTAT-2f), which they call BTAT 2f.
Journal ArticleDOI

Measuring Domain Sizes and Compositional Heterogeneities in P3HT‐PCBM Bulk Heterojunction Thin Films with 1H Spin Diffusion NMR Spectroscopy

TL;DR: In this paper, the application of 1H spin diffusion nuclear magnetic resonance (NMR) is expanded to polymer-fullerene blends for bulk heterojunction (BHJ) organic photovoltaics (OPV) by developing a new experimental methodology for measuring the thin films used in poly-3-hexylthiophene-phenyl C61-butyric acid methyl ester (P3HT-PCBM) OPV devices and by creating an analysis framework for estimating domain size distributions.
