摘要

通过噻吩并[3,2-b]噻吩与单碘-BODIPY 分子的 Sonogashira 偶联反应，合成了四种在中位具有电子捐赠或电子撤回基团的 BODIPY 染料（6a ~ 6d）。所有化合物都通过 1H NMR 和 MALDI-TOF MS 进行了全面表征。通过紫外可见吸收光谱、稳态和时间分辨荧光光谱、双光子激发光谱和循环伏安法研究了它们的光物理和电化学特性。这些共轭染料表现出了有趣的光物理特性，如高摩尔消光系数、大斯托克斯位移和高双光子吸收截面σ2。

Thieno[3,2-b]thiophene-based bridged BODIPY dimers: synthesis, electrochemistry, and one- and two-photon photophysical properties†

Four BODIPY dyes (6a–6d) with electron-donating or electron-withdrawing groups at the meso-position were synthesized by the Sonogashira coupling reaction of 2,5-diethynylthieno[3,2-b]thiophene with mono-iodo-BODIPY moieties. All compounds were fully characterized by ¹H NMR and MALDI-TOF MS. Their photophysical and electrochemical properties were studied by UV-visible absorption spectroscopy, steady-state and time-resolved fluorescence spectroscopy, two-photon excitation spectroscopy and cyclic voltammetry. These conjugated dyes exhibit interesting photophysical properties such as a high molar extinction coefficient, large Stokes shift and high two-photon absorption cross section σ₂.
