observed previously for the analogous naphthalene compounds N1–N12 (Nap[X][EPh], Nap[EPh][E′Ph] (X = Br, I; E/E′ = S, Se, Te). The conformation of the aromatic ring systems and subsequent location of p-type lone-pairs dominates the geometry of the peri-region. The differences in peri-separations observed for compounds adopting differing conformations of the peri-substituted phenyl group can be correlated
已经制备了两个系列的空间拥挤的周边取代的ena啶,它们在A1-A6(Acenap [X] [EPh](Acenap = ena-5,6-diyl; X = Br,I; E = S,Se,Te)和A7–A12中的硫族硫属元素(Acenap [EPh] [E'Ph](Acenap = ena-5,6-二基; E / E'= S, (Se,Te)。还制备了相关的二卤化物A13-A16 Acenap [XX'](XX'= BrBr,II,IBr,ClCl)。相互作用的卤素和硫族元素原子的空间体积占据周围位置。ena系列经历在普遍增加围为分子容纳较重的同源-separation并映射趋势先前为类似萘观察化合物N1-N12(NAP [X] [EPH,NAP [EPH] [E'Ph](X = Br的,I; E / E'= S,硒,碲)的芳族环系及p型孤对后续位置的构象支配的几何形状围-region中的差
