Abstract

A series of dithienopyrrole (DTP) embedded BODIPYs were synthesized and structurally characterized. These BODIPYs have strong absorption in the green region and broad emission in the red region with a large Stokes shift ranging from 3100 to 4200 cm^–1. Interestingly, all three BODIPYs show intramolecular charge transfer interaction (ICT). Intriguingly, both BODIPYs (bis- and tris-BOD) also exhibit excited state symmetry breaking (ES-SB). Single-crystal X-ray analysis unambiguously confirmed the exact structures of all three structurally distinct BODIPYs.

我们合成了一系列嵌入二噻吩吡咯（DTP）的 BODIPYs，并对其进行了结构表征。这些 BODIPYs 在绿色区域有强吸收，在红色区域有宽发射，在 3100 到 4200 cm-1 之间有较大的斯托克斯偏移。有趣的是，这三种 BODIPY 都显示出分子内电荷转移相互作用（ICT）。有趣的是，两种 BODIPY（双-BOD 和三-BOD）还表现出激发态对称性断裂（ES-SB）。单晶 X 射线分析明确证实了这三种结构不同的 BODIPY 的确切结构。

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.
