Development and systematic evaluation of triamine‐based functional deep eutectic solvents for efficient CO2 capture

AIChE Journal, EarlyView.
Abstract The development of advanced absorbents for effectively capturing carbon dioxide is crucial in mitigating greenhouse gas emissions. This study introduced a series of deep eutectic solvents (DESs) for CO2 capture and identified the most promising DESs with the stepwise screening method based on their absorption capacity, absorption rate, thermal

Strategies Towards the Synthesis of N2-Substituted 1,2,3-Triazoles

Anais da Academia Brasileira de Ciências, 2019
The chemistry of 1,2,3-triazoles gained much attention since the discovery of the copper catalyzed Alkyne-azide cycloaddition (CuAAC) reaction which delivers exclusively the 1,4-regioisomer in high yields.

Covalent Attachment of a Platinum(II) Complex inside DNA Duplexes

ChemistryEurope, EarlyView.
Oxidative addition is used for the site‐specific incorporation of an organometallic PtII complex as an artificial nucleobase into a DNA duplex. The platination stabilizes the duplex and confers it with phosphorescence. An organometallic phosphorescent PtII complex is introduced into DNA duplexes via oxidative addition to a tailor‐made artificial ...
