A Dimethylaminophenyl‐Substituted Naphtho[1,2‐ <i>b</i> ]quinolizinium as a Multicolor NIR Probe for the Fluorimetric Detection of Intracellular Nucleic Acids and Proteins

Light up, light up: The fluorimetric detection of different biomacromolecules is accomplished with 3-(4-N,N-dimethylaminophenylnaphtho[1,2-b]quinolizinium as a fluorescent probe. This molecule shows light-up effect in the presence DNA, RNA and bovine serum albumin (BSA) emission energies, intensities, lifetimes. These effects may be used for differentiation between cell compartments.
