异苯并呋喃(IBF)已广泛用于天然产物和多环芳烃的合成中。很少有在稠合的芳族环系统中连接两个IBF实体的例子。在这里,我们介绍了双(IBF),2,7-二(叔丁基)吡喃并[4,5- c:9,10- c ']二呋喃的合成和表征。与双(马来酰亚胺)亲二烯物的反应产生吡喃苯甲酸酯。讨论了bis(IBF)和两个环烷的固态结构。

A new oxanorbornene-fused nanobox encapsulated C70 selectively in solution with a binding constant of (3.2 ± 0.1) × 106 M−1. Reductive aromatization of this nanobox led to observation of a new zigzag carbon nanobelt by mass spectroscopy.

Isobenzofurans (IBF)s have seen widespread use in the synthesis of both natural products and polycyclic aromatic hydrocarbons. There are few examples that have two IBF entities linked in a fused aromaticring system. Here we present the synthesis and characterization of a bis(IBF), 2,7-di(tert-butyl)pyreno[4,5-c:9,10-c′]difuran. Reaction with bis(maleimide) dienophiles gives pyrenophanes. The solid-state

New molecular scaffolds of phenazine and pyrene are constructed by fusing them with oxanorbornene. The C-shaped molecules exhibit two interesting π-π stacking modes of phenazine depending on the substituting groups as revealed by X-ray crystallography. The C- and Z-shaped diastereomers exhibit almost the same charge transfer absorption and emission including positive solvatochromism, which are independent
通过将吩嗪和芘与氧降冰片烯融合来构建新的吩嗪和芘分子支架。C 形分子表现出两种有趣的吩嗪 π-π 堆叠模式,具体取决于 X 射线晶体学揭示的取代基团。C 形和 Z 形非对映异构体表现出几乎相同的电荷转移吸收和发射,包括正溶剂化显色,这与整体分子几何形状无关。
