Prevalent Bioimaging Scaffolds: Synthesis, Photophysical Properties and Applications

This minireview describes the syntheses, structure‐photophysical properties relationship, and bioimaging applications of fluorescent coumarins, xanthenes, BODIPYs, and cyanines. Advantages and disadvantages of the emissive units are also discussed, as are general practical issues that need to be considered when using fluorophores in a biological setting.
