The synthesis of bisalkynylated derivatives of tetrabenzo[a,c,p,r]heptacene and tetrabenzo[a,c,l,n]pentacene via two-/fourfold Stille reactions involving a 9-stannafluorene and suitable tetrabromoacenes is reported. These triphenylene-"winged" heptacenes are surprisingly stable and maintain a significant portion of the electronic properties of heptacenes.
通过涉及 9-锡芴和合适的四溴代苝的二/四步 Stille 反应,合成了四苯并[a,c,p,r]并七苯和四苯并[a,c,l,n]并五苯的双炔基衍生物。这些三苯并[g,i,l,p]芴“翼”并七苯令人惊讶地稳定,并保持了并七苯的部分电子性质。
