    通过Wittig反应合成共轭BODIPY
    摘要:
    通过在简单的室温条件下用烷基/芳基酰化物处理甲酰化的BODIPY,采用Wittig反应以高产率合成缀合的BODIPY。在CH 2 Cl 2中用不同的烷基/芳基化物处理3,5-二甲酰基BODIPYs或α-甲酰基3-吡咯基BODIPY在室温下放置2 h,然后直接在硅胶上进行柱色谱纯化,以约65–90%的收率得到缀合的BODIPY。这是用于合成此类缀合的BODIPY的Knoevenagel和Heck反应的另一种方法。该方法非常有效,我们制备了12个取代的BODIPY,包括胆固醇取代的BODIPY,以证明反应的多功能性。还介绍了这些共轭BODIPY的光谱,电化学和荧光性质。

    19F NMR, X-ray diffraction and for some compounds 2D HSQC and 11B NMR. The absorption, fluorescence and solvatochromism properties were investigated in different solvents. The highest absorption and emission maxima were obtained for compounds having two gem-dibromovinyl groups attached directly at the α-positions.

    We synthesized benzimidazole substituted boron-dipyrromethene 1 (BODIPY 1) by treating 3,5-diformyl BODIPY 2 with o-phenylenediamine under mild acid catalyzed conditions and characterized by using various spectroscopic techniques. The X-ray structure analysis revealed that the benzimidazole NH group is involved in intramolecular hydrogen bonding with fluoride atoms which resulted in a coplanar geometry
    我们通过在温和的酸催化条件下用邻苯二胺处理3,5-二甲酰基BODIPY 2来合成苯并咪唑取代的吡咯亚甲基1(BODIPY 1),并通过各种光谱技术对其进行表征。X射线结构分析表明,苯并咪唑NH基团参与与原子的分子内氢键结合,从而导致BODIPY和苯并咪唑部分之间具有共面的几何形状。与BODIPY 2相比,在BODIPY的3位上存在苯并咪唑基团显着改变了电子性能,这在吸收和荧光带的红移中明显可见,改善了量子产率,并延长了寿命。阴离子结合研究表明,BODIPY 1表现出显着的选择性和特异性对˚F -离子比其他阴离子。的F加成-离子对BODIPY 1导致伴随着从荧光粉红色到蓝色的非荧光视觉检测的颜色变化的荧光的淬灭。识别机制归因于BODIPY和苯并咪唑基团之间的氢键化物引发的破坏,导致(i)BODIPY和苯并咪唑单元之间的非共面几何形状,以及(ii)从苯并咪唑部分到BODIPY单元的光致

    (HRMS), absorption, fluorescence, and electrochemical techniques were used to characterize the compounds. The spectral and electrochemical studies indicated that dipyrromethanyl groups at 3,5-positions of BODIPY are less electron deficient compared to formyl groups at the same positions. The anion binding studies indicated that bis(3,5-dipyrromethanyl) BODIPY compounds containing four pyrrole NH groups

  • 3,5-Diformylboron Dipyrromethenes as Fluorescent pH Sensors
    作者:Sheri Madhu、Malakalapalli Rajeswara Rao、Mushtaque S. Shaikh、Mangalampalli Ravikanth
    DOI:10.1021/ic102499h
    日期:2011.5.16
    A series of boron dipyrromethene (BODIPY) dyes containing two aldehyde functional groups at the 3 and 5 positions have been synthesized in low-to-decent yields in two steps. In the first step, the meso-aryl dipyrromethanes were treated with POCl(3) in N,N-dimethylformamide to afford 1,9-diformylated dipyrromethanes. In the second step, the diformylated dipyrromethanes were first in situ oxidized with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone and then reacted with BF(3)center dot OEt(2) to afford 3,5-diformylboron dipyrromethenes. The X-ray structural analysis indicated that the aldehyde groups are involved in intramolecular hydrogen bonding with fluoride atoms, which may be responsible for the stability of the diformylated BODIPY compounds. The presence of two formyl groups significantly alters the electronic properties, which is clearly evident in downfield shifts in the (1)H and (19)F NMR spectra, bathochromic shifts in the absorption and fluorescence spectra, better quantum yields, and increased lifetimes compared to 3,5-unsubstituted BODIPYs. Furthermore, 3,5-diformylboron dipyrromethenes are highly electron-deficient and undergo facile reductions compared to unsubstituted BODIPYs. These compounds exhibit pH-dependent on/off fluorescence and thus act as fluorescent pH sensors.
