Abstract

Utilizing [14]dehydrobenzoannulene as an electron acceptor, four twisted donor–acceptor architectures were divergently synthesized. Intriguingly, the antiaromatic diazocine core could interrupt electron transfer in the π-frameworks. Benefiting from the junction of dehydrobenzoannulene and carbazoles, all displayed stunning fluorescence and electrochemiluminescence. Anomalously, blue-shifted fluorescence was observed in the electron-donating-group-substituted homologues. Finally, a molecular carbon-based sensor for dopamine detection was constructed. This work provides new insights into the construction and application of molecular carbons.

弯曲π共轭脱氢苯环烯作为供体-受体体系的缺电子核

以[14]脱氢苯并环烯为电子受体，发散合成了四种扭曲的给体-受体结构。有趣的是，反芳香重氮嘧啶核可以中断π-框架中的电子转移。得益于脱氢苯并环烯和咔唑的结合，它们都显示出惊人的荧光和电化学发光。反常的是，蓝移荧光在给电子基团取代的同系物中被观察到。最后，构建了一种分子碳基多巴胺检测传感器。这项工作为分子碳的结构和应用提供了新的见解。

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.
