Journal ArticleDOI
Block Copolymers for Organic Optoelectronics
TL;DR: In this paper, the authors describe both the synthesis and self-assembly of block copolymers for organic optoelectronics, and suggest that block-copolymer strategies previously employed for more classical, insulating polymer systems may be very useful in organic electronics.
Journal ArticleDOI
Effect of Interfacial Properties on Polymer–Nanocrystal Thermoelectric Transport
Nelson E. Coates,Shannon K. Yee,Bryan McCulloch,Kevin C. See,Arun Majumdar,Rachel A. Segalman,Jeffrey J. Urban +6 more
TL;DR: The electrical behavior of a conducting-polymer/inorganic-nanowire composite is explained with a model in which carrier transport occurs predominantly through a highly conductive volume of polymer that exists at the polymer- nanowire interface.
Journal ArticleDOI
Polymer Chain Shape of Poly(3-alkylthiophenes) in Solution Using Small-Angle Neutron Scattering
Bryan McCulloch,Bryan McCulloch,Victor Ho,Megan L. Hoarfrost,Christopher B. Stanley,Changwoo Do,William T. Heller,Rachel A. Segalman,Rachel A. Segalman +8 more
TL;DR: The chain shape of polymers affects many aspects of their behavior and is governed by their intramolecular interactions as mentioned in this paper, and it is clear that a hierarchy of structural features in these polymers controls charge transport.
Journal ArticleDOI
The relationship between morphology and performance of donor–acceptor rod–coil block copolymer solar cells
Yuefei Tao,Yuefei Tao,Bryan McCulloch,Bryan McCulloch,Suhan Kim,Rachel A. Segalman,Rachel A. Segalman +6 more
TL;DR: In this paper, self-assembled functional rod-coil block copolymers (poly(3-hexylthiophene)-b-poly(n-butyl acrylate-stat-acrylate perylene) containing electron donor (Poly(3hexyl thiophene)) and acceptor (perylene) moieties were synthesized, characterized, and studied in photovoltaic devices.
Journal ArticleDOI
Poly(3-alkylthiophene) diblock copolymers with ordered microstructures and continuous semiconducting pathways.
Victor Ho,Bryan W. Boudouris,Bryan McCulloch,Christopher G. Shuttle,Martin Burkhardt,Michael L. Chabinyc,Rachel A. Segalman +6 more
TL;DR: It is demonstrated that other, potentially more useful, nanostructures can be formed when these two interactions are more closely balanced, and careful design of the P3AT moiety allows for a balance between crystallization and microphase separation due to chemical dissimilarity between copolymer blocks.
