Abstract:

An efficient method for synthesizing quinoline derivatives (3a-l) was reported using polyethylene glycol-based sulphonic acid (PEG-SA) and polystyrene-supported polyethylene glycol-based sulphonic acid (PS-PEG-SA) as recyclable catalysts via a friendlier reaction pathway. This strategy is more environmentally sustainable than traditional methods for synthesizing quinoline derivatives, yielding favorable yields and facilitating ease of operation under mild reaction conditions. In presence of PEG-SA/PS-PEG-SA catalyst, carbonyl compounds with an active α-methylene group were added to 2-aminophen

Abstract:

The acid-base properties of naphthalen-1-ol (L1), naphthalene-1,5-diol (L2), and 4-amino-3-hydroxynaphthalene-1-sulphonic acid (L3) were characterized from pH-metric measurements in pure water and in different concentrations (0–4 mol kg−1) of aqueous KCl solutions at the temperature range ofT= (293.15 to 213.15) K at 5 K intervals. The results reveal that naphthalen-1-ol and naphthalene-1,5-diol molecules have two ionisable protons (of the hydroxyl groups) while 4-amino-3-hydroxynaphthalene-1-sulphonic acid has three ionisable protons (hydrogen ion of the hydroxyl group, SO3H, andNH3+).

However, the challenging problems that hamper their application in light emitting devices are loss of signal due to diffusion of the electrochemiluminescence (ECL) reagent out of the detection zone, limited ability to repeatedly cycle an individual luminophore and high reagent consumption. In this work, the main objective was to produce conducting polymers with enhanced electrochemiluminescence by tuning the properties of the po

Abstract:

>Magister Scientiae - MSc<br>Electrochemiluminescence (EeL) is applied for industrial applications that have considerable potential, such as clinical diagnostic, analytical chemistry, and light-emitting devices, due to selectivity, sensitivity for detection and quantification of molecules through generation of fluorescence light when electric current is applied on the materials. In EeL the electrochemical reaction allows for precise control over the time and position of the light emitting reaction. The control over time allows one to synchronise the luminescence and the biochemical reaction u
