Journal ArticleDOI
A Thienoisoindigo-Naphthalene Polymer with Ultrahigh Mobility of 14.4 cm2/V·s That Substantially Exceeds Benchmark Values for Amorphous Silicon Semiconductors
Gyoungsik Kim,Seok-Ju Kang,Gitish K. Dutta,Young-Kyu Han,Tae Joo Shin,Yong-Young Noh,Changduk Yang +6 more
TL;DR: This work reports on an easily attainable donor-acceptor (D-A) polymer semiconductor: poly(thienoisoindigo-alt-naphthalene) (PTIIG-Np), which represents a major step toward truly viable plastic electronics.
Journal ArticleDOI
A Balanced Face-On to Edge-On Texture Ratio in Naphthalene Diimide-Based Polymers with Hybrid Siloxane Chains Directs Highly Efficient Electron Transport
Yiho Kim,Dang Xuan Long,Junghoon Lee,Gyoungsik Kim,Tae Joo Shin,Kyung-Wan Nam,Yong-Young Noh,Changduk Yang +7 more
TL;DR: In this article, structure properties associated with a hybrid siloxane-terminated hexyl chain (SiC6), photophysics, molecular packing, thin-film morphology, and charge carrier transport are reported for two novel naphthalene diimide (NDI)-based polymers.
Journal ArticleDOI
Acceptor–acceptor type isoindigo-based copolymers for high-performance n-channel field-effect transistors
TL;DR: Two acceptor-acceptor (A-A) type copolymers (PIIG-BT and PIIG-TPD) with backbones composed exclusively of electron-deficient units are designed and synthesized and show unipolar n-type operations.
Journal ArticleDOI
Ambipolar Semiconducting Polymers with pi-Spacer Linked Bis-Benzothiadiazole Blocks as Strong Accepting Units
Jonggi Kim,A-Reum Han,A-Reum Han,Jayeon Hong,Gyoungsik Kim,Junghoon Lee,Tae Joo Shin,Joon Hak Oh,Changduk Yang +8 more
TL;DR: In this article, a simplified single-step synthesis of novel vinylene- and acetylene-linked bis-benzothiadiazole (VBBT and ABBT) monomers with enlarged planarity relative to a conventionally used acceptor, benzothienomethane (BT), is presented.
Journal ArticleDOI
Easily Attainable Phenothiazine-Based Polymers for Polymer Solar Cells: Advantage of Insertion of S,S-dioxides into its Polymer for Inverted Structure Solar Cells
TL;DR: Two donor-acceptor (A) type polymers based on a soluble chromophore of phenothiazine (PT) unit that is a tricyclic nitrogen-sulfur heterocycle, have been synthesized by introducing an electron-deficient benzothiadiazole (BT) building block copolymerized with either PT or phenothia-S,S-dioxide (PT-SS) unit as an oxidized form of PT as mentioned in this paper.
