Preparation, characterization, and FET properties of novel dicyanopyrazinoquinoxaline derivatives.
[structure: see text] A series of the title dicyanopyrazinoquinoxaline derivatives have been prepared and characterized by using single-crystal X-ray structure analysis and redox potential measurements. They have strong electron-accepting properties due to the pyrazinopyrazine skeletons as well as the cyano groups. Substituents can be easily introduced at the benzene ring and control the HOMO-LUMO energy gap and the molecular packing. They show clear n-type transistor properties in the FET devices.
