application | BODIPY fluorescent dyes have the advantages of high molar absorbance coefficient, high fluorescence quantum yield, insensitivity of fluorescence signal to solvent polarity and pH, narrow fluorescence spectrum peak, long fluorescence lifetime, moderate redox potential, negligible triplet state, etc. Moreover, BODIPY fluorescent sub-nucleus is relatively stable and has certain chemical activity, the structure is easy to modify, and the absorption and emission wavelengths can be adjusted to the near infrared region. Based on the above advantages, BODIPY fluorescent dyes have attracted more and more attention. |
