Molecular Design of A−D−A Electron Acceptors Towards Low Energy Loss for Organic Solar Cells

Autor: Yuan Guo, Lingyun Zhu, Ruihong Duan, Guangchao Han, Yuanping Yi

Publikováno v: Chemistry – A European Journal. 29

Low energy loss is a prerequisite for organic solar cells to achieve high photovoltaic efficiency. Electron-vibration coupling (i.e., intramolecular reorganization energy) plays a crucial role in the photoelectrical conversion and energy loss process

Low Polarity-Triggered Basic Hydrolysis of Coumarin as an AND Logic Gate for Broad-Spectrum Cancer Diagnosis

Autor: Lingbo Qu, Yuanqiang Sun, Zhaohui Li, Ruihong Duan, Ran Yang, Ke Zhang, Zengqiang Liang

Publikováno v: Analytical Chemistry. 93:12434-12440

The ability to accurately diagnose cancer is the cornerstone of early cancer treatment. The mitochondria in cancer cells maintain a higher pH and lower polarity relative to that in normal cells. A probe that reports signals only when both conditions

Importance of molecular rigidity on reducing the energy losses in organic solar cells: implication from geometric relaxations of A–D–A electron acceptors

Autor: Yuanping Yi, Ling-Bo Qu, Ruihong Duan, Guangchao Han

Publikováno v: Materials Chemistry Frontiers. 5:3903-3910

Because of the emergence of small-molecule acceptors with acceptor–donor–acceptor (A–D–A) structures, organic solar cells (OSCs) have developed rapidly in recent years. Currently, the power conversion efficiencies (PCEs) of the OSCs based on

Nature of the Lowest Singlet and Triplet Excited States of Organic Thermally Activated Delayed Fluorescence Emitters: A Self-Consistent Quantum Mechanics/Embedded Charge Study

Autor: Guangchao Han, Yuanping Yi, Zeyi Tu, Ruihong Duan, Taiping Hu

Publikováno v: Chemistry of Materials. 31:6665-6671

Thermally activated delayed fluorescence (TADF) is dictated by the properties of the lowest singlet (S1) and triplet (T1) excited states. Both small energy difference (ΔEST) and large spin–orbit co...

Electronic, optical, and charge transport properties of A-π-A electron acceptors for organic solar cells: Impact of anti-aromatic π structures

Autor: Qingxu Li, Yuanping Yi, Guangchao Han, Ruihong Duan, Yuan Guo, Yan Zeng

Publikováno v: Chinese Chemical Letters. 30:211-216

Organic solar cells based on acceptor-π-acceptor (A-π-A) electron acceptors have attracted intensive attention due to their increasing and record power conversion efficiencies. To date, almost all of the reported A-π-A electron acceptors are based
