Luminescent Cd(ii)–organic frameworks with chelating NH₂ sites for selective detection of Fe(iii) and antibiotics

Abstract

Cd(ii) frameworks with amino functionalized sites show high sensitivity for the detection of Fe(iii) and antibiotics such as nitrofurazone.

Water‐Stable Coordination Polymers as Dual Fluorescent Sensors for Highly Oxidizing Anions Cr2O72− and MnO4−

“…In general, those CPs based on the ligands with large π‐conjugated system tend to exhibit striking fluorescence . Meanwhile, according to the previous studies, d 10 metal ions such as Cd II and Zn II can be utilized to construct fluorescent materials . Based on above considerations, a π‐conjugated ligand 2‐(4‐(( E )‐2‐(pyridine‐2‐yl)vinyl)styryl)pyridine (2‐bpeb) was synthesized successfully and then reacted with Cd II and Zn II salts.…”

A Water‐Stable Uranyl Organic Framework as a Highly Selective and Sensitive Bifunctional Luminescent Probe for Fe3+ and Tetracycline Hydrochloride

“…[7,8] Therefore, the detection and sensing of antibiotic molecule and Fe 3 + are of great significance in the fields of medicine, agronomy,l ife science and environmentals cience. [9][10][11] Up to now,av ariety of analytical detection techniques have been reported, including electrochemical assays,g as chromatography,l iquid chromatography,e tc. However,t hese detectionm ethods are often complicated operation, time consuming, and costly.…”

CdII‐Organic Frameworks Fabricated with a N‐Rich Ligand and Flexible Dicarboxylates: Structural Diversity and Multi‐Responsive Luminescent Sensing for Toxic Anions and Ethylenediamine

“…MOFs constructed from d 10 metal ions together with conjugated organic ligands, which are deemed as potential choice of fluorescence materials . The solid fluorescence emission spectra of L , 1 , 2 and 3 were measured at room temperature (Figure S8).…”

“…MOFs constructed from d 10 metal ions together with conjugated organic ligands, which are deemed as potentialc hoice of fluorescencem aterials. [26] The solid fluorescencee mission spec-tra of L, 1, 2 and 3 were measured at room temperature (Figure S8). The emission bands of L, 1, 2 and 3 are observed at 465 nm (l ex = 400 nm), 440 nm (l ex = 380 nm), 443 nm (l ex = 380 nm) and 454 nm (l ex = 395 nm), respectively.A sf ar as we know,t he double bond is consist of s and p bonds, and the emission of organic ligandsa re usually ascribed to p*!p and/ or p*!ne lectronic transitions.…”
