Abstract

AbstractThe Expansion of modern industry underscores the urgent need to address heavy metal pollution, which is a threat to human‐health and environment. Efforts are underwent to develop precise technologies for detecting heavy metal ions (M+‐ion). One promising approach involves the use of Conjugated Microporous Polymers (CMPs) modified with Triphenylamine (TPA) anderylene (Peryl), known as TPA‐Peryl‐CMP, which emits strong refluorescence. Various analytical techniques, such as Brunauer–Emmett–Teller analysis, Fourier transform infrared (FTIR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, and thermogravimetric analysis (TGA), are utilized to characterize the synthesized TPA‐Peryl‐CMP and understand its functional properties. In addition to its remarkable fluorescence behavior, TPA‐Peryl‐CMP shows promise as a sensor for Fe3+ ions using a turn‐off strategy. Due to its exceptional stability and robust π‐electron system, this platform demonstrates remarkable sensitivity and selectivity, significantly improving detection capabilities for specific analytes. Detailed procedures related to the mechanism for detecting Fe3+ ions are outlined for sensing Fe3+ ions, revealing a notably strong linear correlation within the concentration range of 0–3 µM, with a correlation coefficient of 0.9936 and the Limit of detection (LOD) 20 nM. It is anticipated that development of such a kind of TPA‐Peryl‐CMP will observe broader applications in detecting various analytes related to environmental and biological systems.
