10-dihydrodipyrazino[2,3-b:2′,3′-c]pyrazines 11–20. These compounds have rather small molecular size but have strong intramolecular charge-transfer chromophoric system. They have strong fluorescence in solution and some have fluorescence even in the solid state which are very important to evaluate their electroluminescence property as an emitter for electroluminescence devices. The physical, structural, and
对2-氨基-3-氯-5,6-二氰基吡嗪进行碱催化的分子间环化反应,得到5,10-二取代基-2,3,7,8-四氰基-5,10-二氢二吡嗪并[2,3- b:2 ′,3′-c]吡嗪11–20。这些化合物具有相当小的分子大小,但是具有强的分子内电荷转移发色体系。它们在溶液中具有很强的荧光,有些甚至在固态也具有荧光,这对于评估其作为电致发光器件的发射器的电致发光性能非常重要。这些新的2,3,7,8-tetracyano-5,10-dihy-drodipyrazino [2,3- b:2′3′- e的物理,结构和电子性质使用紫外-可见光谱和Pariser-Parr-Pople分子轨道计算方法研究了对吡嗪。
