Dual-Responsive and Reusable Optical Sensors Based on 2,3-Diaminoquinoxalines for Acidity Measurements in Low-pH Aqueous Solutions

Autor: Anastasia Bolshakova, Alla Lemeune, Elizaveta Ermakova

Publikováno v: Sensors; Volume 23; Issue 6; Pages: 2978

This work is focused on the age-old challenge of developing optical sensors for acidity measurements in low-pH aqueous solutions (pH < 5). We prepared halochromic (3-aminopropyl)amino-substituted quinoxalines QC1 and QC8 possessing different hydrophi

Functionalised Imidazoporphyrins and their application in catalysis

Autor: Abdulaeva, Inna

Publikováno v: Theoretical and/or physical chemistry. Université Bourgogne Franche-Comté; Institut Frumkin de Chimie Physique et d'Electrochimie (Moscou), 2017. Russian. ⟨NNT : 2017UBFCK053⟩

A broad series of functionalized imidazo[4,5-b]porphyrins was synthesized by the acid-catalyzed condensation of 2,3-dioxo-5,10,15,20-tetraarylchlorins with aromatic aldehydes. Both steric and electronic features of meso-aryl substituents influence on
