  A New Synthesis of Functional Dyes from 2-Acenaphtho[1,2-c]pyrrole

  摘要：

  Incorporation of acenaphtho[1,2-c]pyrrole units into the pi-conjugated systems is very effective to get the narrow HOMO-LUMO gap materials, and the absorption spectra of pi-conjugated polymers, porphyrins, and boron dipyrromethene dyes fused with acenaphthene rings are extensively red-shifted.

• A series of π-expanded coplanar BODIPY dyes with deep-red emission: Synthesis, optical properties, and application in amplified spontaneous emission

  dipyrromethene (BODIPY)-derived dyes are a class of superior emitters, and a classic BODIPY structure has absorption and emission at ∼500 nm. To meet the practical application requirements, this work was dedicated to the design and synthesis of BODIPY emitters covering the deep-red region with a high emission quantum yield. Aromatic rings and a well-known electron-withdrawing group, –CF3, were introduced

  硼二吡咯亚甲基 (BODIPY) 衍生染料是一类优异的发射体，经典的 BODIPY 结构在~500 nm 处具有吸收和发射。为了满足实际应用需求，本工作致力于设计和合成覆盖深红色区域、具有高发射量子产率的BODIPY发射体。芳香环和著名的吸电子基团 –CF 3，被引入π展开的BODIPY结构中。详细讨论了这些 BODIPY 发射器，包括它们的热稳定性和光学参数，以及它们的光动力治疗性能。讨论了BODIPY光物理性能与其取代基之间的相关性。研究发现，π扩展共面共轭链的形成成功地将BODIPY发射转移到深红色区域（626 nm），并具有高量子产率（0.99）。然而，BODIPY内消旋-C 上的-CF 3修饰猝灭了其发射。ASE（放大自发发射）效应的阈值能量为 980 μJ，效率为 5.5%。使用这些 BODIPY 染料作为光敏剂，细胞活力降低至 9.0 ± 4.6%。

  A series of pi-expanded boron-dipyrromethenes (BODIPYs) fused with aromatic rings at beta,beta-positions, such as benzene, acenaphthylene, and benzofluoranthene were prepared by the reaction of BF(3)center dot OEt(2) with bicyclo[2.2.2]octadiene-fused dipyrromethene and the subsequent retro Diels-Alder reaction. These BODIPYs exhibited the absorptions and the fluorescence emissions over wide range of visible-near infrared region at 500-800 nm. BODIPYs composed of two fluorantho[8,9-f]isoindoles absorbed and emitted at red-region over 750 nm with absolute fluorescence quantum yield (Phi(f)) of ca. 0.3, although they are unstable under air in room light. BODIPY composed fluorantho[8,9-f]isoindole and acenaphtho [1,2-c]pyrrole was stable and showed a bright fluorescence emission at 695 nm with high Phi(f) of 0.70. (C) 2010 Elsevier Ltd.
