A new family of α, α directly linked bisBODIPYs was developed through a MoCl₅-mediated intramolecular oxidative reaction. Due to the coplanar structure of the two conformationally locked BODIPY units, these bisBODIPYs showed well-extended conjugations and gave strong near-infrared absorptions and emissions with maxima around 760 and 780 nm, respectively, with high fluorescence quantum yields of ≤0.84. These dyes were successfully applied for in vitro and in vivo fluorescence imaging by taking advantage of their beneficial photophysical properties.

构象受限的α，α直接连接的BisBODIPYs作为高度荧光的近红外吸收染料

通过MoCl ₅介导的分子内氧化反应，开发了一个新的α，α直接连接的bisBODIPYs家族。由于两个构象锁定的BODIPY单元的共面结构，这些bisBODIPY表现出良好的共轭性，并具有很强的近红外吸收和发射，最大值分别在760 nm和780 nm左右，且荧光量子产率≤0.84。这些染料通过利用其有益的光物理特性，成功地应用于体外和体内荧光成像。
