The aim of this contribution is to provide an introduction and a brief summary of the principle of fluorescence molecular sensors specific to inorganic phosphate (Pi) and inorganic pyrophosphate (PPi) as well as their applications. In our introduction we describe the impact of both Pi and PPi in the living organism and in the environment, followed by a description of the principle of fluorescence molecular sensors and the sensing mechanism in solution. We then focus on exciting research which has emerged in recent years on the development of fluorescent sensors specific to Pi and PPi, categorized by chemical interactions between the sensor and the target molecule, such as hydrogen bonding, coordination chemistry, displacement assay, aggregation induced emission or quenching, and chemical reactions.

该贡献的目的是提供对无机磷酸盐（Pi）和无机焦磷酸盐（PPi）特定的荧光分子传感器原理及其应用的简介和简要概述。在我们的介绍中，我们描述了Pi和PPi对活生物体和环境的影响，然后描述了荧光分子传感器的原理以及溶液中的传感机制。然后，我们专注于近年来针对Pi和PPi的荧光传感器的发展而进行的激动人心的研究，该传感器按传感器与目标分子之间的化学相互作用进行分类，例如氢键，配位化学，位移测定，聚集诱导发射或淬灭，以及化学反应。
