Tang, Tengxuan; Wang, Jing; Xu, Dongmei published the artcile< Synthesis of a novel hyperbranched polymer and its application in multi-channel sensing Fe3+>, COA of Formula: C30H36N4O2, the main research area is hyperbranched polymer fluorescent sensor iron.
A novel hyperbranched polymer was designed and synthesized as a spectral probe for Fe3+. The polymer showed high selectivity and sensitivity to Fe3+ in CH3CN/H2O (75/25, volume/volume). Fe3+ caused a new peak at 560 nm in UV-Vis absorption, a 31 nm fluorescence red shift, a 35-fold enhancement in fluorescence intensity at 575 nm and an 8.3-fold enhancement in fluorescence quantum yield, accompanied by a visual color change from colorless to pink and a fluorescence from dark to bright orange. The colorimetric and fluorescent detection limits were 1.29 and 1.88 μM, resp. The detection was almost not interfered by other common metal cations. The polymer could be applied in assaying Fe3+ in real sample with similar precision to that of at. absorption spectroscopy.
