Synthesis and Photophysics of BF<sub>2</sub>-Rigidified Partially Closed Chain Bromotetrapyrroles: Near Infrared Emitters and Photosensitizers
We report the synthesis, crystallographic, optical, and triplet and singlet oxygen generation properties of a series of BF2‐rigidified partiallyclosedchainbromotetrapyrroles as nearinfraredemitters and photosensitizers. These novel dyes were efficiently synthesized from a nucleophilic substitution reaction between pyrroles and the 3,5‐bromo‐substituents on the tetra‐ and hexabromoBODIPYs and absorb
我们报告了一系列BF 2刚性化的部分闭链溴四吡咯作为近红外发射器和光敏剂的合成,晶体学,光学以及三重态和单重态氧的产生特性。这些新型染料是通过吡咯与四溴代和六溴代BODIPY上的3,5-溴代取代基之间的亲核取代反应有效合成的,并在高摩尔消光系数的近红外区域(681–754 nm)吸收。它们的荧光发射(708-818 nm)和单线态氧的产生特性受这些染料的两个未配位吡咯单元上的烷基取代以及溶剂极性的影响很大。其中,染料4 ca和4 da 表现出良好的单线态氧生成效率和良好的近红外荧光发射(在所研究的不同溶剂中,荧光量子产率为0.14-0.43)。
Regioselective Stepwise Bromination of Boron Dipyrromethene (BODIPY) Dyes
Halogenated BODIPYs are important synthetic precursors and potential sensitizers for photodynamic therapy (PDT). Electrophilic bromination of pyrrolic-unsubstituted BODIPYs using bromine regioselectively generated mono- to heptabromoBODIPYs in a stepwise fashion in good to excellent yields. These resultant bromoBODIPYs were applied for regioselective substitution and Suzuki coupling reaction to generate
