In this work, a rhodamine derivative was developed as a colorimetric and ratiometric fluorescent probe for Hg2+. It exhibited a highly sensitive fluorescence response toward Hg2+. Importantly, studies revealed that the probe could be used for ratiometric detection of Hg2+, with a low detection limit of 0.679 μM. The mechanism of Hg2+ detection using compound 1 was confirmed by ESI-MS, 1H NMR, and HPLC. Upon the addition of Hg2+, the rhodamine receptor was induced to be in the ring-opening form via an Hg2+-promoted hydrolysis of rhodamine hydrazide to rhodamine acid. In addition to Hg2+ detection, the naphthalimide-rhodamine compound was proven to be effective in cell imaging.

《Triazole-stabilized fluorescence sensor for highly selective detection of copper in tea and animal feed》 was published in Food Chemistry in 2020. These research results belong to Qiu, Suyan; Wei, Yihua; Tu, Tianhua; Xiang, Jianjun; Zhang, Dawen; Chen, Qinglong; Luo, Linguang; Lin, Zhenyu. Formula: C30H30N10 The article mentions the following:

A triazole-stabilized fluorescence sensor is developed for copper detection in the study. Tris-(benzyltriazolylmethyl)amine (TBTA) is used to improve the sensitivity and stability for the sensing system. A series of comparative experiments are performed with and without TBTA. In the presence of TBTA, the fluorescence decrease ratio is enhanced from 2.46 to 118.25; the detection limit is reduced from 67 nM to 3.6 nM; the higher selectivity toward copper compared to the other metal ions is verified, including K+, Ca2+, Cd2+, Zn2+, Mg2+, Mn2+, Pb2+, Hg2+, Fe3+ and Cr3+. Besides, the sensing system is successfully applied for copper determination in complex tea samples and chicken feed samples with the recovery range of 91.67-116.8%. A good consistency between the presented sensor and the flame atom absorbance spectrometry (FAAS) is confirmed by the low relative errors with the range from -2.39% to 7.02%. In the experimental materials used by the author, we found Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine(cas: 510758-28-8Formula: C30H30N10)

《Selective Chemical Modification of DNA with Boronic Acids by On-Column CuAAc Reactions》 was published in Synthesis in 2020. These research results belong to Debiais, Megane; Vasseur, Jean-Jacques; Muller, Sabine; Smietana, Michael. Safety of Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine The article mentions the following:

The use of the Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction for the preparation of oligonucleotide conjugates is by now familiar. However, the selective introduction of boronic acids into DNA and RNA sequences by CuAAC reactions has long been considered impossible due to the incompatibility of the boronic acid moiety with copper salts. Here we describe two new methods for the selective on-column functionalization of oligonucleotides with boronic acids via two different CuAAC reactions. The first one allows the introduction of a phenylboronic acid at the 5′-extremity of oligonucleotides, while the selective – positioning of the modification can be achieved with the second one. Both methods were applied to the DNA and RNA series (up to a 20-mer) with good isolated yields and excellent purity. These results illustrate the potential of the reported methods for selective incorporation of boronic acids into oligonucleotides. In the experiment, the researchers used many compounds, for example, Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine(cas: 510758-28-8Safety of Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine)

The author of 《Nonpyrolyzed Fe-N Coordination-Based Iron Triazolate Framework: An Efficient and Stable Electrocatalyst for Oxygen Reduction Reaction》 were Huang, Zheng-Hong; Xie, Nan-Hong; Zhang, Min; Xu, Bo-Qing. And the article was published in ChemSusChem in 2019. Product Details of 288-36-8 The author mentioned the following in the article:

Pyrolyzed base-metal-based metal-organic frameworks (MOFs) with FeNx coordination are emerging as nonprecious metal catalysts for electrochem. oxygen reduction reaction (ORR). However, surprisingly, nonpyrolyzed MOFs involving Fe-N coordination have not been explored for the ORR. This study concerns the catalytic performance of a semiconducting nonpyrolyzed iron triazolate framework (FeTa2) for ORR in alk. electrolyte. The FeTa2 catalyst is studied as composites with different amounts of conductive Ketjenblack carbon (KB). The performance of these FeTa2-x KB (x denotes the KB/FeTa2 weight ratio) composites by onset and half-wave potentials of ORR appears to be superior to most previously documented nonpyrolyzed MOFs. Characterization by elemental anal., FTIR spectroscopy, XPS, and cyclic voltammetry suggest that N-FeIII-OH- sites at the surface of FeTa2 function as the catalytic active sites. This FeTa2 also shows very stable activity during ORR, as supported by accelerated durability test of the FeTa2-x KB sample (20 000 cycles, ca. 90 h). The framework structure of FeTa2 remains intact during the durability test, which would help to explain its excellent catalytic durability. This would be the first study demonstrating efficient and stable ORR catalysis by a nonpyrolyzed Fe-N coordination-based MOF material.

In 2022,Kitaoka, Satoshi; Nishinaka, Shinnosuke; Nobuoka, Kaoru published an article in Heterocycles. The title of the article was 《Substituent effects on physical properties of azole based ionic liquids》.Application In Synthesis of 1H-1,2,3-Triazole The author mentioned the following in the article:

The effect of the substituents on the phys. properties of azole based ionic liquids, such as m.p. and viscosity is investigated. The introduction of electron-withdrawing groups to azolate anions and electron-donating groups to azolium cations delocalized the charge of anion or cation, and reduced the viscosity and m.p. of the ionic liquids The charge of the azolium cations and the azolate anions are distributed not only on the azole ring but also on the substituents. The decrease in the charge d. of anions and cations in ionic liquids weakens the interaction between the anions and the cations, resulting in a decrease in the viscosity of the ionic liquids Such a method of delocalizing the anion and cation charges of triazole-based ionic liquids by introduction of the substituents can be applied to reduce the viscosity of various ionic liquids as reaction medium and electrolytes. In the part of experimental materials, we found many familiar compounds, such as 1H-1,2,3-Triazole(cas: 288-36-8Application In Synthesis of 1H-1,2,3-Triazole)
