| Abstract: |
| Potassium permanganate（KMnO4），as a powerful oxidant，is widely used in chemical production，water purification and wastewater treatment．While excessive emission can cause severe environmental pollution and excessive intake can lead to irreversible organ necrosis．Moreover，it is one of the most frequently used raw materials in preparing improvised explosives．Hence，a rapid，highly sensitive and visual identification of trace KMnO4 is of great significance for environment monitoring and public security．Recently，fluorescence technique has been widely applied for KMnO4 detection due to the features of high sensitivity and selectivity，rapid response，various optional function group and visualization．At present，the fluorescent involved functional materials for detecting KMnO4 can be divided as nanomaterials，coordination polymers and hybrid materials，the detection mechanism relies on inner filter effect（IFE），fluorescence resonance energy transfer（FRET），static quenching，redox and complexation. Among them，the IFE-based method is the main mechanism employed in KMnO4 detection due to the advantages of simple operation，sensitive response and material reusability．Hence，this review systematically summarizes the recent progress within five years of the IFE-based approaches for KMnO4 determination．It starts with a brief introduction of strategic designs focusing on performance improvement of IFE-involved sensing detection towards KMnO4．The influence from the modulation of the mono-/multi-emission wavelength on the sensing sensitivity is comprehensively discussed．To end，a prospective is forecasted regarding the future development of IFE-involved sensing strategy for KMnO4 detection and the potential application，providing a guide for the IFE-based sensing platform to ultra-sensitively detect KMnO4． |
