Understanding the Electronic Properties of Acceptor–Acceptor′–Acceptor Triads [PDF]

open access: yesACS Omega, 2019
In order to develop new organic materials for optoelectronic applications, a fundamental understanding of the electronic properties of specific chromophore combinations must be realized. To that end, we report "model" acceptor (A)-acceptor' (A')-acceptor (A) triads in which the pendants (A') we selected are well-known components of organic ...

Sulfonium Salts as Acceptors in Electron Donor‐Acceptor Complexes

open access: yesAngewandte Chemie, 2023
AbstractThe photoactivation of electron donor‐acceptor complexes has emerged as a sustainable, selective and versatile strategy for the generation of radical species. Electron donor‐acceptor (EDA) complexation, however, imposes electronic constraints on the donor and acceptor components and this can limit the range of radicals that can be generated ...

Tetrachlorophthalimides as Organocatalytic Acceptors for Electron Donor–Acceptor Complex Photoactivation

open access: yesJournal of the American Chemical Society, 2022
Excitation of photoactive electron donor-acceptor (EDA) complexes is an effective way to generate radicals. Applications in a catalytic regime typically use catalytic donors. Herein, we report that readily available electron-poor tetrachlorophthalimides can act as effective organocatalytic acceptors to trigger the formation of EDA complexes with a ...

Design Principles for the Acceptor Units in Donor–Acceptor Conjugated Polymers

open access: yesACS Omega, 2022
More than 50 different acceptor units from the experimental literature have been modeled, analyzed, and compared by using the computationally extracted data from the density functional theory (DFT) perspective for tetramer structures in the form of (D-B-A-B)4 (D, donor; A, acceptor; B, bridge) with fixed donor and bridge units.

Organic solar cells based on acceptor-functionalized diketopyrrolopyrrole derivatives [PDF]

open access: yes, 2015
This work was supported by the EPSRC (grants EP/E036244 and EP/I00343X).The synthesis and characterization of three solution processable diketopyrrolopyrrole (DPP) derivatives featuring acceptor units attached to the core by alkyne linker units is ...

Circular Photoinduced Electron Transfer in a Donor‐Acceptor‐Acceptor Triad [PDF]

open access: yesAngewandte Chemie International Edition, 2017
AbstractAn electron‐donor‐acceptor‐acceptor (D‐A1‐A2) triad has been developed that provides the first proof‐of‐concept for a photoinitiated molecular circuit. After photoexcitation into an optical charge‐transfer transition between D and A1, subsequent thermal electron‐transfer from A1.− to A2 is followed by geometric rearrangement in the D.+‐A1‐A2 ...

Acceptor-Controlled Transfer Dehydration of Amides to Nitriles

open access: yes, 2019
Palladium-catalyzed dehydration of primary amides to nitriles efficiently proceeds under mild, aqueous conditions via the use of dichloroacetonitrile as a water acceptor. A key to the design of this transfer dehydration catalysis is the identification of

Development of non-fullerene electron acceptors for efficient organic photovoltaics

open access: yesSN Applied Sciences, 2022
Compared to fullerene based electron acceptors, n-type organic semiconductors, so-called non-fullerene acceptors (NFAs), possess some distinct advantages, such as readily tuning of optical absorption and electronic energy levels, strong absorption in the
