Impact of Isomeric Structures on Transistor Performances in Naphthodithiophene Semiconducting Polymers

Autor: Itaru Osaka, Shoji Shinamura, Toru Abe, Kazuo Takimiya

Publikováno v: Journal of the American Chemical Society. 133:6852-6860

Four isomeric naphthodithiophenes (NDTs) with linear and angular shapes were introduced into the polythiophene semiconductor backbones, and their field-effect transistor performances were characterized. The polymers bearing naphtho[1,2-b:5,6-b']dithi

Publikováno v: Organic letters. 16(1)

Dithiophene-fused tetracyanonaphthoquinodimethanes (DTTNAPs) were synthesized and evaluated as n-channel organic semiconductors. DTTNAPs, regardless of isomeric structures and substituents, have low-lying LUMO energy levels (∼4.6 eV below the vacuu
