摘要

分子梯因其定义明确的熔合环结构作为有机电子学中有前途的材料而受到特别关注。在此，我们提出了一个分子阶梯的合成和性质，该分子阶梯具有4重反芳五边形环嵌入在2.000(1)nm的主链中。晶体学分析显示其扭曲的骨干，导致紧密堆积，最短的接触为3.210(9)Å。其高达3e-氧化和4e-还原的强劲氧化还原行为分别源于二对二萘和二对四烯的特性。该阶梯在单晶有机场效应晶体管中的最大空穴迁移率为μh = 0.035 cm2 V-1 s-1。

A 2 nm Molecular Ladder with a Twisted Backbone

Molecular ladders are of particular interest for their well-defined fused-ring architectures as promising materials in organic electronics. Herein, we present the synthesis and properties of a molecular ladder featuring 4-fold antiaromatic pentagonal rings embedded into the 2.000(1) nm backbone. The crystallographic analysis revealed its twisted backbone, causing tight packing with a shortest contact of 3.210(9) Å. The robust redox behavior of up to 3e^– oxidation and 4e^– reduction originates from the diindenonaphthalene and diindenotetracene characters, respectively. This ladder exhibited a maximum hole mobility of μ_h = 0.035 cm² V^–1 s^–1 in single-crystal organic field-effect transistors.

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
