A Water Stable Cd^II‐based Metal‐Organic Framework as a Multifunctional Sensor for Selective Detection of Cu²⁺ and Cr₂O₇^2– Ions

Abstract

A water stable tetrazolate‐containing metal‐organic framework, [Cd2(L)(OH)(H2O)2]n (1) [H3L = 5‐(4‐(tetrazol‐5‐yl)phenyl)isophthalic acid], was synthesized under solvothermal conditions and structurally characterized. Compound 1 displays a three dimensional porous network with one dimensional tubular channels based on trinuclear cluster [Cd3(μ3‐OH)N4C] units. Notably, 1 exhibits highly sensitive response to Cu2+ and Cr2O72– through luminescence quenching effects with the detection limit of 0.666 ppm for Cu2+ and 0.846 ppm for Cr2O72–, respectively. The possible mechanism of the luminescence quenching was discussed in detail.

Synthesis, Structure, and Properties of Cadmium(II) Centered Chiral Coordination Polymer based on (R)‐6‐(1‐Carboxyethoxy)‐2‐naphthoic Acid

“…As a basic feature of nature, chirality plays an important role in life activities . Currently, the construction of chiral coordination polymers has attracted enormous interest as functional materials for potential applications in enantiomeric separation,, asymmetric catalysis,, fluorescence, nonlinear optics, and so on. In particular, luminescent chiral coordination polymers have become more focused as chemosensors for the probe of metal cations, small organic molecules and nitro explosives due to their easy operation, high selectivity and sensitivity …”

Synthesis and Crystal Structure of Amino Acid Modified NDI Lanthanide Coordination Complex

“…They are often applied to solar conversion, electroluminescence, n type semiconductor materials, gas storage, ion recognition, bioluminescent probe, etc . Metal‐organic frameworks (MOFs), as a new kind of porous materials, have important applications in light‐electricity, catalysis, adsorption, and separation fields . The derivatives of NDI are lack of electrons with good capability in thermal stability and light electricity.…”
