摘要

为了研究二聚体硼-二吡啶(BODIPYs)的光谱性质变化,合成了四种BODIPY衍生物,包括在中间位置取代一个呋喃基的单体BODIPY和以呋喃基为桥的二聚体BODIPY。通过核磁共振和质谱对合成的四种BODIPY衍生物进行了表征。研究了单体(mT1和mT2)和二聚体(biT1和biT2)在8种不同溶剂中的紫外可见吸光度和荧光发射等光物理性质。此外,通过密度泛函理论计算,考虑了它们的结构性质与光学性质的关系。使用呋喃基团的两个BODIPY单元之间的共价连接对二聚体BODIPY的光学性质有深远的影响。我们相信,对二聚体BODIPY的合成和物理性质的了解将在未来设计新的BODIPY衍生物和预测其光谱特性方面具有广阔的前景。

Photophysical properties of furan-bridged dimeric boron-dipyrromethene derivatives (BODIPYs)
In order to investigate the changes in the spectroscopic properties of dimeric boron-dipyrromethenes (BODIPYs), four BODIPY derivatives are synthesized, including a monomer BODIPY in which a furyl group is substituted at the meso position and a dimer BODIPY with a furan group as a bridge. The four synthesized BODIPY derivatives are characterized through nuclear magnetic resonance and mass spectrometry. Photophysical properties such as ultraviolet–visible absorbance and the fluorescence emission of monomers (mT1 and mT2) and dimers (biT1 and biT2) are studied in eight different solvents. In addition, the relationship of their structural properties and optical properties are also considered through density functional theory calculations. The covalent link between the two BODIPY units using a furan group has a profound effect on the optical properties of the dimeric BODIPYs. We believe that an understanding of the synthesis and physical properties of dimeric BODIPYs will have a promising perspective in designing new BODIPY derivatives and predicting their spectroscopic characteristics in the future.

期刊介绍: The Journal of Chemical Research is a peer reviewed journal that publishes full-length review and research papers in all branches of experimental chemistry. The journal fills a niche by also publishing short papers, a format which favours particular types of work, e.g. the scope of new reagents or methodology, and the elucidation of the structure of novel compounds. Though welcome, short papers should not result in fragmentation of publication, they should describe a completed piece of work. The Journal is not intended as a vehicle for preliminary publications. The work must meet all the normal criteria for acceptance as regards scientific standards. Papers that contain extensive biological results or material relating to other areas of science may be diverted to more appropriate specialist journals. Areas of coverage include: Organic Chemistry; Inorganic Chemistry; Materials Chemistry; Crystallography; Computational Chemistry.
