Efficient Two-Photon Absorbing Acceptor-π-Acceptor Polymethine Dyes

The Journal of Physical Chemistry A, 2010
We present an experimental and theoretical investigation of the linear and nonlinear optical properties of a series of acceptor-pi-acceptor symmetrical anionic polymethine dyes with diethylamino-coumarin-dioxaborine terminal groups and different conjugation lengths.

Diestervinyl-Functionalized Acceptor-Acceptor Type Dithienylethenes with Efficient Photochromic Performance

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2022
Exploring novel dithienylethenes (DTEs) with efficient photochromism has drawn increasing attention in virtue of the potential applications for photoelectric functional materials. In this contribution, we presented two novel acceptor-acceptor (A-A) type DTE derivatives (4a and 4b) by incorporating the diestervinyl moieties with strong electron ...

A Narrow‐Bandgap n‐Type Polymer with an Acceptor–Acceptor Backbone Enabling Efficient All‐Polymer Solar Cells

Advances in Materials, 2020
Narrow‐bandgap polymer semiconductors are essential for advancing the development of organic solar cells. Here, a new narrow‐bandgap polymer acceptor L14, featuring an acceptor–acceptor (A–A) type backbone, is synthesized by copolymerizing a dibrominated

Reducing the Exciton Binding Energy of Donor-Acceptor-Based Conjugated Polymers to Promote Charge-Induced Reactions.

Angewandte Chemie, 2019
Exciton binding energy has been regarded as a crucial parameter for mediating charge separation in polymeric photocatalysts. Minimizing the exciton binding energy of the polymers can increase the yield of charge-carrier generation and thus improve the ...

Fused Benzothiadiazole: A Building Block for n‐Type Organic Acceptor to Achieve High‐Performance Organic Solar Cells

Advances in Materials, 2019
Narrow bandgap n‐type organic semiconductors (n‐OS) have attracted great attention in recent years as acceptors in organic solar cells (OSCs), due to their easily tuned absorption and electronic energy levels in comparison with fullerene acceptors ...

Asymmetric Catalytic Reactions of Donor-Acceptor Cyclopropanes.

Angewandte Chemie, 2020
Due to the synergistic "push-pull" effect of vicinal electron-donating and electron-withdrawing groups, donor-acceptor (D-A) cyclopropanes have been recognized as one of the most powerful reagents to generate polyfunctional reactive intermediates after a

Donor–acceptor–donor polymers utilizing pyrimidine-based acceptors

Reactive and Functional Polymers, 2014
Abstract Pyrimidine acceptor groups were coupled with thienyl, 3,4-ethylenedioxythienyl (EDOT), and 3,4-(2,2-dibutylpropylenedioxy)thienyl (ProDOT-Bu2) donor groups in an attempt to synthesize stable n-doping polymers. Monomers were synthesized using a triorganoindium coupling reaction and characterized using nuclear magnetic resonance spectroscopy ...
