distances of 3.658(8) and 3.787(8) Å and a small bowl slip of 0.086(6) Å. The tight bowl packing is accompanied by notable molecular geometry adjustments of the individual PAHs. The bowl depth increased for corannulene (Δ = +0.019 Å) and decreased for sym-pentakis(trifluoromethyl)corannulene (Δ = −0.011 Å), facilitating enhancement of concave–convex interactions along the stacks. The parallel alignment of
通过使用两个具有互补结构和性质的碗形多环
芳烃(PAH),即C 20 H 10和C 5 -C 20 H 5(CF 3),完成了新的晶体供体-受体有机杂化物的设计合成。5。产物[((C 20 H 10)·(C 20 H 5(CF 3)5)]·C 6 H 4 Cl 2)的X射线结构表征表明,形成了交替排列的C 20 H排列的柱状堆叠体10和C 20 H 5(CF 3)5分子,质心到质心距离为3.658(8)和3.787(8)Å,小碗滑移为0.086(6)Å。密密麻麻的碗包装伴随着各个多环
芳烃的显着分子几何结构调整。碗皮深度对corannulene(Δ= +0.019Å)增加,对对称五(三
氟甲基)corannulene(Δ= -0.011Å)减小,有利于沿堆垛的凹凸相互作用。一维列的平行排列受到涉及C 6 H 4 Cl 2的多种分子间相互作用的支持 用作结晶溶剂,形成固态的无限二维网络。
