Hexa-armed dansyl end-capped poly(e-caprolactone) star polymer with phosphazene core ( N 3 P 3 -(PCL-Dansyl) 6 ) was prepared in a two-step synthetic procedure including ring opening polymerization (ROP) of e-caprolactone (e-CL) and esterification reactions. The obtained fluorescence-active polymer was employed as a fluorescent probe towards certain nitroaromatic compounds (2,4,6-trinitrotoluene (TNT), 2,4-dinitrotoluene, 2,6-dinitrotoluene, 2-nitrotoluene, 3-nitrotoluene, 2,4,6-trinitrophenol (picric acid), 2,4-dinitrophenol, 4-nitrophenol, and 1,2-dinitrobenzene). Fluorescence intensity of N 3 P 3 -(PCL-Dansyl) 6 was decreased gradually upon the addition of nitroaromatic compounds and the highest quenching efficiency was found to be 100% with TNT. Besides, N 3 P 3 -(PCL-Dansyl) 6 gave exceptionally selective response toward nitroaromatic compounds, even in the presence of toxic metal cations such as Pb 2+ , Co 2+ , Hg 2+ , Mn 2+ , Cd 2+ and Zn 2+ .
