New semi-ladder polymers for ambipolar organic light-emitting transistors

Autor: Yachu Du, Dafei Yuan, Mohammad A. Awais, Luping Yu

Publikováno v: Chemical communications (Cambridge, England). 58(81)

Organic light-emitting transistors (OLETs) combine the light-emitting and gate-modulated electrical switching functions in a single device. Over the past two decades, progress has been made in developing new fluorescent semiconductors and device engi

Photoinduced cationic polycondensation in solid state towards ultralow band gap conjugated polymers

Autor: Luping Yu, Mohammad A. Awais, Forwood Wiser, Zhen Zhang, Valerii Sharapov, Xunshan Liu

Publikováno v: Journal of Materials Chemistry C. 8:7026-7033

A photoinduced cationic polycondensation towards the synthesis of a thieno[3,4-b]thiophene (TT) based homopolymer PTT-L was described. The reaction mechanism was investigated by employing a series of control experiments. It was found that the polymer

Foldable semi-ladder polymers: novel aggregation behavior and high-performance solution-processed organic light-emitting transistors

Autor: Wei Chen, Xunshan Liu, Mohammad A. Awais, Luping Yu, Dafei Yuan, Andriy Neshchadin, Valerii Sharapov, Mrinal K. Bera

Publikováno v: Chemical Science

A critical issue in developing high-performance organic light-emitting transistors (OLETs) is to balance the trade-off between charge transport and light emission in a semiconducting material. Although traditional materials for organic light-emitting

Synergy between Photoluminescence and Charge Transport Achieved by Finely Tuning Polymeric Backbones for Efficient Light-Emitting Transistor

Autor: Dafei Yuan, Mohammad A. Awais, Andriy Neshchadin, Wei Chen, Luping Yu, Xunshan Liu, Valerii Sharapov

Publikováno v: Journal of the American Chemical Society. 143(13)

The lack of design principle for developing high-performance polymer materials displaying strong fluorescence and high ambipolar charge mobilities limited their performance in organic light-emitting transistors (OLETs), electrically pumped organic la

Synthesis of Alternating Donor–Acceptor Ladder‐Type Molecules and Investigation of Their Multiple Charge‐Transfer Pathways

Autor: Na Zhang, Zhengxu Cai, Alexander S. Filatov, Luping Yu, Mohammad A. Awais

Publikováno v: Angewandte Chemie International Edition. 57:6442-6448

We describe the synthesis as well as the optical and charge-transport properties of a series of donor-acceptor (D-A) ladder-type heteroacenes. These molecules are stable, soluble, and contain up to 24 fused rings. Structural analyses indicated that t

Exploration of Syntheses and Functions of Higher Ladder-type π-Conjugated Heteroacenes

Autor: Luping Yu, Mohammad A. Awais, Zhengxu Cai, Na Zhang

Publikováno v: Chem. 5:245-247

Summary Ladder-type heteroacenes with well-defined structures and highly planar and delocalized π-electrons are an important class of materials for potential applications in organic electronics. The incorporation of heteroatoms into the ladder backb
