Journal ArticleDOI
Recent Progress in High-Mobility Organic Transistors: A Reality Check.
Alexandra F. Paterson,Saumya Singh,Kealan J. Fallon,Thomas Hodsden,Yang Han,Bob C. Schroeder,Hugo Bronstein,Martin Heeney,Iain McCulloch,Thomas D. Anthopoulos +9 more
TL;DR: Overall, this review brings together important information that aids reliable OTFT data analysis, while providing guidelines for the development of next-generation organic semiconductors.
Journal ArticleDOI
Exploiting Excited-State Aromaticity To Design Highly Stable Singlet Fission Materials.
Kealan J. Fallon,Peter Budden,Enrico Salvadori,Enrico Salvadori,Alex M. Ganose,Christopher N. Savory,Lissa Eyre,Simon Dowland,Qianxiang Ai,Stephen Goodlett,Chad Risko,David O. Scanlon,Christopher W. M. Kay,Christopher W. M. Kay,Akshay Rao,Richard H. Friend,Andrew J. Musser,Hugo Bronstein +17 more
TL;DR: Extension of the theoretical analysis to almost ten thousand candidates reveals an unprecedented degree of tuneability and several thousand potential fission-capable candidates, whilst clearly demonstrating the relationship between triplet aromaticity and singlet-triplet energy gap, confirming this novel strategy for manipulating the exchange energy in organic materials.
Journal ArticleDOI
Manipulating molecules with strong coupling: harvesting triplet excitons in organic exciton microcavities
Daniel Polak,Rahul Jayaprakash,T. P. Lyons,Luis A. Martínez-Martínez,Anastasia Leventis,Kealan J. Fallon,Harriet Coulthard,David G. Bossanyi,Kyriacos Georgiou,Anthony J. Petty,John E. Anthony,Hugo Bronstein,Joel Yuen-Zhou,Alexander I. Tartakovskii,Jenny Clark,Andrew J. Musser,Andrew J. Musser +16 more
TL;DR: In this article, it was shown that spin-2 triplet-pair states can also play a major role in polariton dynamics, observing polariton population transferred directly from the triplet manifold via triplet triplet annihilation.
Journal ArticleDOI
Synthesis and Exciton Dynamics of Donor-Orthogonal Acceptor Conjugated Polymers: Reducing the Singlet–Triplet Energy Gap
David M.E. Freeman,Andrew J. Musser,Jarvist M. Frost,Hannah L. Stern,Alexander K. Forster,Kealan J. Fallon,Alexandros G. Rapidis,Franco Cacialli,Iain McCulloch,Tracey M. Clarke,Richard H. Friend,Hugo Bronstein +11 more
TL;DR: This work introduces a general approach to reduce the singlet-triplet energy gap in fully conjugated polymers, using a donor-orthogonal acceptor motif to spatially separate electron and hole wave functions and finds that the mechanisms of both processes are driven by excited-state mixing between π-π*and charge-transfer states.
Journal ArticleDOI
Indolo-naphthyridine-6,13-dione Thiophene Building Block for Conjugated Polymer Electronics: Molecular Origin of Ultrahigh n-Type Mobility
Kealan J. Fallon,Nilushi Wijeyasinghe,Eric F. Manley,Eric F. Manley,Stoichko D. Dimitrov,Syeda Amber Yousaf,Raja Shahid Ashraf,Warren Duffy,Anne A. Y. Guilbert,David M.E. Freeman,Mohammed Al-Hashimi,Jenny Nelson,James R. Durrant,Lin X. Chen,Lin X. Chen,Iain McCulloch,Tobin J. Marks,Tracey M. Clarke,Thomas D. Anthopoulos,Hugo Bronstein +19 more
TL;DR: In this paper, the authors present the synthesis and characterization of four conjugated polymers containing a novel chromophore for organic electronics based on an indigoid structure, which exhibit extremely small band gaps of ∼1.2 eV, impressive crystallinity, and extremely high n-type mobility exceeding 3 cm2 V s −1.
