Multicomponent click polymerization for the synthesis of coumarin containing 1,4-polytriazoles and their application as dye adsorbent

Multicomponent Synthesis of Fluorescent Thiazole–Indole Hybrids and Thiazole-Based Novel Polymers

“…After having success in the synthesis of bis-thiazoles by multicomponent reaction and in continuation of our recent work on the methodology development and synthesis of novel polymers, we then turned our attention to preparing novel polymers using this multicomponent reaction. Using bis-thioamides ( 10a and 10b ) and following the similar reaction conditions as mentioned for 9a , we have prepared two novel thiazole-based polymers 11a and 11b in high yields (Scheme ).…”

One-pot multicomponent polymerization towards heterocyclic polymers: a mini review

“…Several high-molecular-weight polymers with good yields were synthesized, resulting in effective dye adsorbents with high selectivity. 63 He Junnan, et al developed Cu( i )-catalyzed MCP using diynes, sulfonyl azides, and a series of tumor microenvironment (TMEs)-responsive, cleavable diols to produce biodegradable poly( N -sulfonylimidate)s that respond differently to tumor microenvironments, exhibiting excellent degradation performance and high molecular weights. The conjugation of tetraphenyl porphyrin to polymer side chains enhances fluorescence intensity and singlet oxygen quantum yield for photodynamic therapy.…”

Simultaneous removal of Pb2+ and direct red 31 dye from contaminated water using N-(2-hydroxyethyl)-2-oxo-2H-chromene-3-carboxamide loaded chitosan nanoparticles

“…The new coumarin chelating-adsorbent improved the Pb( ii ) and Cd( ii ) accumulation step which enhanced the sensitivity of Pb( ii ) and Cd( ii ) by anodic stripping voltammetry greatly. More recently, Bhaumick and Choudhury 35 reported the preparation and application of coumarin containing 1,4-polytriazoles for different water-soluble dyes. They reported high adsorption efficiency for methylene blue and attributed this efficiency to the presence of moieties required for π–π, cation–π, and ion–dipole interactions.…”
