garnered interest due to their potential use in semiconductor applications and as models to study through-bond and through-space electronic interactions. Herein we report the development of a novel 3D-symmetric rylene imide buildingblock, triperyleno[3,3,3]propellane triimides (6), that possesses three perylene monoimide subunits fused on a propellane. This buildingblock shows several promising characteristics
刚性三维 (3D) 多环芳烃 (PAH),特别是 3D 纳米石墨烯,由于其在半导体应用中的潜在用途以及作为研究键合和空间电子相互作用的模型而引起了人们的兴趣。在此,我们报告了一种新型 3D 对称萘嵌苯酰亚胺结构单元三苝烯[3,3,3]丙烷三酰亚胺 ( 6 )的开发,它具有融合在丙烷上的三个苝单酰亚胺亚基。该结构单元显示出几个有前途的特性,包括高溶解度、大π表面、电子接受能力和多种反应位点。此外,该结构单元与不同的反应兼容,可以轻松产生不同化学性质的准D 3h对称纳米结构(9、11和13)。对于 3D 纳米结构,与各个亚基相比,我们观察到红移吸收最大值和吸收系数的放大,表明亚基之间存在分子内电子耦合。此外,尽管π-共轭部分的分子间重叠相当有限,但9的微板在10 -3 cm 2 V -1 s -1范围内的不同方向上表现出相当的迁移率。这些发现表明,这些准D 3h对称萘嵌苯酰亚胺具有作为 3D

Areno-anellated [3.3.n]propellanes with n = 2, 3, and 4 are easily accesible by palladium-catalyzed domino coupling processes of the pentalene system 8 with various aryl iodides. The X-ray structure investigations reveled a noteworthy elongation of the central CC single bond of these propellanes to ca. 162 pm.

symmetric triperyleno[3.3.3]propellanes (TPRPs), which are composed of three perylene units peri-fused on [3.3.3]proppellane, have been synthesized and their electronic properties characterized. Unsubstituted TPRP assembles into two-dimensional honeycomb-like networks. TPRP displays a bathochromic-shifted absorption band in its absorption spectrum and shows well-separated one-electron redox waves in a cyclic

The strained propellane 5 is efficiently synthesized from 3 in three reaction steps including epoxidation, organometallicarylation and final cyclization by intramolecular Friedel–Crafts alkylation.
Solvothermal condensation with terephthalaldehyde gave an amorphous polymeric solid with moderate BET surface area, different from precursor molecules. The solid displayed good adsorption capacities for hydrocarbon gases and vapors. Because of multiple CH/π interactions, the adsorption was efficient even in low-pressure region for n-butane and larger alkanes, providing good selectivity over smaller alkanes
