Fluorescent aliphatic hyperbranched polyether: chromophore-free and without any N and P atoms

Abstract

The strong fluorescence, in both the solution and the bulk state, of a chromophore-free aliphatic hyperbranched polyether which does not contain N and P atoms was reported for the first time. Effects of concentration and solvent solubility were measured. Its ethanol solution shows a strong blue-green fluorescence (Y_u = 0.11–0.39), and its fluorescence shows a strong selective quenching with respect to Fe³⁺.
