摘要

我们报告了系链位置如何影响蒽衍生物的构象、刚性和（基）光学性质。1,5-系链和1,10-系链（分别为长对角系链和短对角系链）会产生类似的扭曲，而短对角系链衍生物显示出更大的构象灵活性，显著影响荧光和旋向行为。值得注意的是，由于热可接近的扭曲构象，短的和长对角的辛基系蒽表现出逆温度依赖的CD响应。这些发现突出了系绳位置在功能性弯曲芳烃设计中的关键作用。

The Right Strap: The Role of Tether Position and Length in Acene Distortion.

We report how the tether position affects the conformation, rigidity, and (chiro)optical properties in anthracene derivatives. While 1,5- and 1,10-tethers (long and short diagonal tethering, respectively) induce comparable twisting, short diagonal tethered derivatives display greater conformational flexibility, significantly impacting fluorescence and chiroptical behavior. Notably, short and long diagonal octyl-tethered anthracenes exhibit inverse temperature-dependent CD responses attributed to thermally accessible twisted conformers. These findings highlight the critical role of the tether position in the design of functional curved aromatics.

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.
