Mark E. Ziffer,Sae Byeok Jo,Yun Liu,Hongliang Zhong,Joseph C. Mohammed,Jeffrey S. Harrison,Alex K.-Y. Jen,David S. Ginger +7 more
TL;DR: In this paper, the authors compare two regioregular analogues (referred to as P1 and P2) of the widely used donor-acceptor copolymer poly[4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b:4,5-b′]dithiophene-co-3-fluorothieno[3,4-b]thiophene2-carboxylate], which differ only in the orientation of a fluor
Journal ArticleDOI
Achieving excellent tradeoffs among optical, chemical and thermal properties in second-order nonlinear optical chromophores
TL;DR: In this paper, a new class of second-order nonlinear optical chromophores resulting from the replacement of the most reactive CN group in tricyanovinylthiophene derivatives with aryl units, are designed and synthesized.
Journal ArticleDOI
Direct surface functionalization of indium tin oxide via electrochemically induced assembly
TL;DR: In this paper, a new methodology was developed to covalently bond organic functional monolayer on ITO through electrochemically induced assembly of organophosphonic acids, which can be deposited under typical electrochemical conditions at ambient temperature.
Journal ArticleDOI
Facile Incorporation of Pd(PPh3)2Hal Substituents into Polymethines, Merocyanines, and Perylene Diimides as a Means of Suppressing Intermolecular Interactions

TL;DR: X-ray structures show that the resulting Pd(PPh3)2Hal groups greatly reduce intermolecular π-π interactions, which generally exhibit solution-like absorption spectra in films, whereas their Hal analogues exhibit features attributable to aggregation.
Journal ArticleDOI
Regiospecific N-alkyl substitution tunes the molecular packing of high-performance non-fullerene acceptors

TL;DR: In this article, a series of benzotriazole (Bz) fused-ring π-core has been designed and synthesized for organic solar cells (OSCs), and the molecular packing of mBzS-4F, AN6SBO-4Fs, and EHN6SEH-4f single crystals was analyzed using X-ray crystallography in order to provide a comprehensive understanding of the correlation between the molecular structure, the charge-transporting properties, and the solar cell performance.
