Aggregation-Induced Emission Poly(meth)acrylates for Photopatterning via Wavelength-Dependent Visible-Light-Regulated Controlled Radical Polymerization in Batch and Flow Conditions

“…43 Effective controlled RDRP can also be carried out via the photoreduction of Cu(II) in the presence of a greater than two-fold excess of appropriate tertiary amine ligands, such as Me 6 TREN. 52 In our previous work, we had hypothesized that irradiation occurs into both a free ligand absorbance and the alkyl bromide initiator and not into the copper(II) complex. 53,54 Recently, Barner-Kowollik et al probed the wavelength dependence of the photochemically induced copper-mediated polymerization of methyl acrylate between 305 and 550 nm, reporting the reactivities and comparing monomer conversion, molecular weights, and dispersity with the absorption spectrum of the copper(II) complex.…”

Self-healing and mechanical performance of dynamic glycol chitosan hydrogel nanocomposites

“…[40][41][42] Among them, coppermediated reversible deactivation radical polymerization (Cu-RDRP) has been established as a versatile method for the preparation of well-defined polymers with a broad monomer and solvent compatibility. [43][44][45][46] Specifically, aqueous Cu-RDRP based on the rapid disproportionation of Cu(I)Br/Me 6 TREN at low temperatures, is an efficient, simple and fast radical polymerization technique that can offer excellent control over molecular weight and well defined water-soluble polymers at various architectures in <10 min. [47][48][49][50] In this present study we introduce a faster way to access welldefined amphiphilic benzaldehyde modified crosslinkers using as precursors ABA telechelic copolymers from a simple, environmental and fast polymerization technique in water.…”

Rapidly self-deoxygenating controlled radical polymerization in water via in situ disproportionation of Cu(i)

“…Reversible Deactivation Radical Polymerization (RDRP) methods, including atom-transfer radical polymerization (ATRP), 1,2 single electron transfer-living radical polymerization (SET-LRP), 3,4 reversible addition-fragmentation chain-transfer polymerization (RAFT) 5,6 and nitroxide-mediated polymerization (NMP) [7][8][9] have provided access to an increasing range of well-dened materials with sophisticated architectures, various functionalities and controlled (macro)molecular characteristics. [10][11][12] Until recently, a notable hindrance for their development has been oxygen intolerance. Consequently, controlled radical polymerization processes conducted in the presence of oxygen are inhibited due to the ability of oxygen to react with carbon-centred radicals, leading to the formation of peroxy radicals via side reactions.…”
