Robust Fabrication of Fluorescent Cellulosic Materials via Hantzsch Reaction

“…[ 1 ] These reactions allow three or more reactants to convert to products in one pot, manifesting high reaction efficiency. Nowadays, more and more MCRs have been utilized to obtain new functional polymers with unique blocks, such as macrocycles [ 2 ] and polymacrocycles, [ 3 ] and dedicated functions including specific capacity for bonding metals, [ 4 ] sticking tissues, [ 5 ] UV screening, [ 6 ] data storage, [ 7 ] fluorescent labeling, [ 8,9 ] and formaldehyde detection, [ 10 ] greatly expanding the applied scope of MCRs.…”

“…Hantzsch reaction could form fluorescent 1,4‐dihydropyridine (DHP) ring in the presence of β‐diketone, aldehyde and amine. [ 9,10,30 ] Herein, we propose the fabrication of fluorescent cellulosic materials via Hantzsch reaction. An “acetoacetylation‐multicomponent” strategy was employed as a versatile and facile method for modifying cotton fabric ( Figure a).…”

Preparation of Block Copolymer Nano‐Objects with Embedded β‐Ketoester Functional Groups by Photoinitiated RAFT Dispersion Polymerization

“…In particular, AEMA bearing with β‐ketoester group has been widely used in multicomponent reaction for the preparation of a variety of functional polymers that find applications in bioimaging, vitrimer, anti‐cancer, and surface modification. [ 70–76 ] Moreover, β‐ketoester group of AEMA can also be used to coordinate with lanthanide ions for the preparation of lanthanide‐doped materials. [ 77–79 ] Currently, there is only one literature reported RAFT‐mediated dispersion polymerization of AEMA for the preparation of β‐ketoester‐functionalized block copolymer nano‐objects.…”

Antioxidant Polymers via the Kabachnik‐Fields Reaction to Control Cellular Oxidative Stress

“…Examples of such MCRs include the Passerini, Ugi, Biginelli, Hantzsch, Kabachnik–Fields (KF), and Mannich reactions. [ 15–32 ] MCRs are suitable for the preparation of polymer antioxidants for several reasons. Some antioxidative groups such as phenol are compatible with many MCRs and can be easily introduced into polymer chains without losing their antioxidative ability.…”
