Methylation-controlled photophysical tuning in isolated acridine cations revealed by cryogenic fluorescence spectroscopy and TD-DFT.
Acridine derivatives, such as proflavine, acriflavine, and acridine orange, have been used extensively in biology and biomedicine as fluorescent probes by forming DNA-intercalating complexes. This approach benefits from a comprehensive understanding of their photophysical properties. In this context, we studied the flu...
