A Highly Selective and Sensitive Chemosensor for Iron Cations Based on Fluoran Dye

摘要：

The development of sensitive chromogenic probes has been receiving much attention in recent years because of the potential application in clinical biochemistry and environment. Numerous literature reports have appeared that explore colorimetric sensing of main-group and transition-metal ions, such as K+, Hg2+, Cu2+, Cd2+, Zn2+, and Ag+1-2. Interestingly, relatively few examples have been reported as sensors for Fe2+ and Fe3+ cations. Both Fez+ and Fe3+ play vital roles in many biological processes, and deficiencies or excesses of these ions are toxic or can lead to a variety of diseases3. Though the human body can regulate iron to some extent, detection and analysis of bioactive iron represents an important healthcare challenge. Herein, we designed and synthesized a new highly selective chemosensor based on fluoran dye for iron cations, name: N-(2-(2-hydroxybenzylideneamino) ethyl) iso-indolin-l-one-fluoran (5) as shown in Fig. 1.
