资源简介：
New n-type heteroaromatic quinoids with 1,4-diazacyclopentadien-2-ylidene terminals were prepared. These quinoids possess strong electron-accepting properties, comparable to dicyanomethylene analogues. Both the radical anions and dianions were generated by metal reduction using 3% Na−Hg in THF and were spectroscopically characterized.
