The development of fluorescent sensors for highly sensitive detection of multiple environmental contaminants is highly promising, but still remains to be a challenge up to date. In this work, we provide a highly water-dispersible sulfonated conjugated microporous polymers (S-CMP) based fluorescent sensor array that can be used for high-throughput detection of multiple organic/inorganic contaminants. This S-CMP was synthesized via a two-step process, including a Pd-catalyzed coupling reaction and a sulfonation process. It is differentiated twelve metal ions using principal component analysis (PCA) on the basis of distinguished fluorescent responses of the sensor array on metal ions. Moreover, it is also identified a series of organic solvents by this S-CMP-based sensor by virtue of its unique fluorescence-emitting and color response. This work opens up the design of sulfonate-grafted CMP in environmental pollution detection and expands the application scope of CMP.

用于高度灵敏地检测多种环境污染物的荧光传感器的开发是非常有前途的，但是迄今为止仍然是一个挑战。在这项工作中，我们提供了一种基于水的高度分散的磺化共轭微孔聚合物（S-CMP）荧光传感器阵列，可用于多种有机/无机污染物的高通量检测。该S-CMP通过两步法合成，包括Pd催化的偶联反应和磺化法。使用主成分分析（PCA），可以根据传感器阵列对金属离子的不同荧光响应来区分十二种金属离子。此外，该基于S-CMP的传感器还因其独特的荧光发射和颜色响应而识别出一系列有机溶剂。
