Device operation mechanism of field-effect transistors with high mobility donor-acceptor polymer semiconductors

Autor: Takayuki Okachi, Tomoya Kashiki, Kenichiro Ohya

Publikováno v: SPIE Proceedings.

The mechanism of high field-effect mobility observed recently in transistors with donor-acceptor alternating polymers was experimentally and numerically examined. It was revealed that the trapped electrons injected from the drain electrode into the l

Autor: Naoyuki Yanai, Itaru Osaka, Ryusuke Sugimoto, Kazuo Takimiya, Eigo Miyazaki, Noriko Takemura, Tomoya Kashiki, Shoji Shinamura

Publikováno v: Organic letters. 14(18)

Selective functionalization protocols of naphtho[1,2-b;5,6-b′]dithiophene (NDT3) by combining protection of the thiophene α-positions and direct borylation on the naphthalene core are described, which allows synthesizing a number of new NDT3-based

ChemInform Abstract: Alkylated 2,6-Bis(dicyanomethylene)-2,6-dihydrobenzo[1,2-b:4,5-b′]dithiophenes: New Soluble n-Channel Organic Semiconductors for Air-Stable OFETs

Autor: Tomoya Kashiki, Kazuo Takimiya, Eigo Miyazaki

Publikováno v: ChemInform. 40

New solution-prosessable n-channel organic semiconductors were developed based on a 2,6-bis(dicyanomethylene)-2,6-dihydrobenzo[1,2-b:4,5-b′]dithiophene core. The OFETs showed n-channel transistor c...

ChemInform Abstract: One-Pot Synthesis of Benzo[b]thiophenes and Benzo[b]selenophenes from o-Halo-Substituted Ethynylbenzenes: Convenient Approach to Mono-, Bis-, and Tris-Chalcogenophene-Annulated Benzenes

Autor: Hirokazu Kuwabara, Masahiro Kohara, Shoji Shinamura, Eigo Miyazaki, Masaaki Ikeda, Tomoya Kashiki, Kazuo Takimiya

Publikováno v: ChemInform. 40

A convenient one-pot procedure for the synthesis of benzo[b]thiophenes and selenophenes from readily available o-halo-ethynylbenzene precursors is described. Regardless of the substituent on the acetylene terminus or the number of cyclization moietie
