Bis-pseudoindoxyls: A new class of single benzene-based fluorophores for bioimaging applications

Fluorophores are chemical compounds or molecules that absorb light energy at one wavelength and re-emit it as light at a longer, lower-energy wavelength, acting as glowing tags or markers. The absorption process is known as excitation, and the re-emission is visible as fluorescent light, which makes these molecules crucial for biological imaging, diagnostics, and tracing cellular molecules like proteins or lipids under normal or various infectious conditions.
