Advancement and future challenges of metal–organic coordination polymers: A case study of optical sensor for the detection of the environmental contaminants

Abstract

Fast industrialization, increasing population, rapid urbanization, and the greediness of creamy layer in the society without the issues of caring the sustainability of ecosystem are the main out of many reasons behind the environmental catastrophe. The ecological balance is disturbed with the noxious materials generated from the uncontrolled use of modern science and technology and also unscientific and unsystematic societal growths. To save the modern civilization, a fast‐track task is the monitoring of the toxic materials for the maintenance of sustainable ecological health and their utilization in a circular economy. Accordingly, optical methods are employed for the detection and estimation of environmental contaminants for immediate monitoring. The stability and structural tunability of the coordination polymeric (CPs) materials make them promising optical sensors for easy, low cost, reliable, selective, and sensitive detection of toxic ions/molecules. The crystallinity, thermal, mechanical, magnetic, and optical stability and flexibility of the CPs play a beneficial role for the accurate and stress‐free recognition of the toxicants. In this review, the recent developments as well as the outlook on the sensing of pollutants at a very low concentration level using CPs as selective and specific sensors by spectro‐fluorometric method are summarized. The progresses and challenges in the fabrication of hybrid materials and understanding their structure property correlations are described with an aim to motivate and facilitate the future researchers to perform research in the area.

Facile construction of an anthracene-decorated highly luminescent coordination polymer for the selective detection of explosive nitroaromatics and the mutagenic pollutant TNP

“…In recent years, a large number of CPs have been developed as chemosensors for their suitability in the detection of molecules, anions, or cations that are present in a given medium, such as a solution, air, drinking water, blood, tissue, and waste effluents. [8][9][10][11][12][13][14][15][16] Several methodologies are available in the eld of recognition involving chemosensors, such as atomic absorption spectroscopy (AAS), spectrophotometry, chromatography, titrimetry, inductively coupled plasma atomic emission spectrometry (ICP-AES), inductively coupled plasma mass spectrometry (ICP-MS), uorescence spectrometry, uorimetry, potentiometry, and X-ray uorescence spectrometry. Of these, the uorescence approach rises to the top to serve sensing activities due to its quick response, high sensitivity, low cost, user-friendly operation, and capacity to evaluate genuine samples.…”

Correlation in Structural Architecture toward Fabrication of Schottky Device with a Series of Pyrazine Appended Coordination Polymers

“…In most cases, pyridyl or imidazolyl ligands serve as N donors, and dicarboxylates function as O-donor ligands to bridge the metal knots to fabricate metal–organic networks. − Naphthalene dicarboxylate is more conjugated than the alkyne/alkene/phenyl dicarboxylates and has been used to design the CPs that respond smartly to external stimuli . The properties of CPs depend on the electronic and steric effect of linkers (organic/inorganic), electronic configuration and periodic position of the metal knot, and the structural architecture of the material along with the surroundings for electrical communication.…”
