Abstract

Covalent organic polymers (COPs) received much attention due to their application in diverse fields, especially in sensing. A highly efficient fluorescence sensor in selective detection of Fe3+ions is necessary to develop. In this work, we successfully synthesized a new covalent organic polymers named COP-TP, with the excellent performance in selective detection of Fe3+ions, the quenching mechanism mainly due to the energy transfer process. The above results show COP-TP has the possibility to be a new candidate in selective detection as Fe3+ions sensor.

Highlights

Covalent organic polymers (COPs) [1,2], as a new class of organic materials have drawn lots of attention due to their attractive properties with pre-disigned structure [3], stable-band [4], and good dispersion[5] as well as the chemical and physical stability
The precipitate was collected by filtration, repeatedly washed by Soxhlet extraction for 24 h, and dried in vacuum to give COP-TP as powder
The results showed the COP-TP will not be affected by the Co2+, Zn2+, Cr3+, Cu2+, Mg2+ ions

Summary

Introduction

Covalent organic polymers (COPs) [1,2], as a new class of organic materials have drawn lots of attention due to their attractive properties with pre-disigned structure [3], stable-band [4], and good dispersion[5] as well as the chemical and physical stability. There are many materials used to act as sensors to detect metal ions, such as metal-organic polymers (MOPs) [13,14,15,16] and small organic molecules [17,18,19,20]. Covalent organic polymers act as sensors to detect Fe3+ ions are rarely reported, a COP with excellent selective ability to Fe3+ ions is promising to design.
