Novel 2‐4‐[1‐(pyridine‐2‐yl)‐1H‐pyrazol‐3‐yl] phenyl}‐2H‐naphtho [1,2‐d] [1,2,3] triazolyl fluorescent derivatives were synthesized from p‐nitrophenylacetic acid and 2‐hydrazino pyridine through Vilsmeier–Haack and diazotization reactions. Photophysical properties were evaluated, and results show that compounds have good fluorescence quantum yields. Thermal analysis showed that they are reasonably
