Abstract/Summary

A Prussian blue (PB)​-​embedded coordination polymer (COP) was prepd. by simple incorporation of PB into a COP composed of 1,​1,​2,​2-​tetrakis(4-​carboxyphenyl)​ethane and the Zn ion during the synthesis of COP. The PB-​COP was prepd. as micro-​sized particles with green emission (490 nm) from the strongly fluorescent tetraphenylethene group in the solid state through aggregation-​induced emission. The PB-​COP showed particle shape with sizes ranging from 1 to 6 μm. As the PB in PB-​COP efficiently adsorbed Cs ions, the microstructure of PB-​COP was degraded to smaller particles, along with a concomitant decrease in the green fluorescence of the PB-​COP. Such a decrease in the green emission of PB-​COP was used as a signal for the presence of Cs ions, in which the limit of detection for Cs ions was found to be 73.8 ppb. The hybridized material of the PB-​COP can be used as both an efficient adsorbent and a sensor for Cs ions, achieving simultaneous removal and detection.
