Fluorescent nucleosides (dUbmz) with desirable fluorescence quantum yield (Φ) are synthesized from almost non-fluorescent 5-fdU and o-phenylenediamine derivatives. The fluorescence of these nucleosides is quite sensitive to pH and organic solvents. 4-Methoxybenzene-1,2-diamine was used for the detection of 5-fdU among natural nucleosides.
