摘要

成功地合成了一类新的环π-扩展杂芳烯低聚物——u型二苯并氮二烯环同型二聚体。核磁共振波谱和DFT计算暗示了大环的独特拓扑结构。环状二聚体在溶液和固体状态下均显示出强烈的绿到黄色荧光。值得注意的是，它显示出酸响应的颜色变化和质子化后的光致发光“关闭”响应。杂芳烃大环是开发先进光电材料和超分子主客体体系的多功能支架。

Synthesis and Photophysical Properties of Cyclic Homodimer of U-Shaped Dibenzophenazinylene

A new class of cyclic π-extended heteroarylene oligomer─cyclic homodimer of U-shaped dibenzophenazinylene─has been successfully synthesized and characterized. NMR spectroscopy and DFT calculations implicated the unique topologies of the macrocycle. The cyclic dimer displays intense green-to-yellow fluorescence in both solution and the solid state. Remarkably, it shows acid-responsive color changes and a photoluminescence “turn-OFF” response upon protonation. The heteroaromatic macrocycle represents a versatile scaffold for the development of advanced optoelectronic materials and supramolecular host–guest systems.

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.
