In this paper, we describe the synthesis of asymmetric functional POEGMA-b-P(ST-co-VBA) copolymers in methanol, yielding one-pot polymerization a range nanoparticle morphologies, including spherical micelles, worm-like, rod-like micelles and vesicles. The presence aldehyde group was then exploited to form crosslinks or conjugate chemotherapy compounds, such as doxorubicin, via pH-breakable bonds (Schiff base imine) directly preformed nanoparticles. influence morphologies on MCF-7 breast...
A simple and efficient route to gold-polymer nanoparticle composites is described. Our versatile synthetic exerts facile control over polymer morphology, including micelles, rod-like structures, vesicles, all easily attainable from a single polymerization taken different monomer conversions. Specifically, poly[oligo(ethylene glycol) methacrylate]-b-poly(dimethylaminoethyl methacrylate)-b-poly(styrene) (POEGMA-b-PDMAEMA-b-PST) triblock copolymers were synthesized using induced self-assembly...
Nanoparticles with various morphologies such as micelles, worm‐like/rod‐like and spherical vesicles are made using a polymerization‐induced self‐assembly (PISA) approach via one‐pot RAFT dispersion polymerization. On polymerization/self‐assembly, we report concurrent highly efficient loading of guest molecules within the nanoparticle structures. Different morphologies, worm‐like, rod‐like, vesicles, achieved by gradually increasing number‐average degree polymerization (DP n ) PST block times...
We report a versatile synthetic method for the in situ self-assembly of magnetic-nanoparticle-functionalized polymeric nanomorphologies, including spherical micelles and rod-like worm-like vesicles. Poly(oligoethylene glycol methacrylate)-block-(methacrylic acid)-block-poly(styrene) (POEGMA-b-PMAA-b-PST) triblock copolymer chains were simultaneously propagated self-assembled via polymerization-induced (PISA) approach. Subsequently, carboxylic acid groups copolymers used to complex an iron...
Abstract Phenacyl morpholine‐4‐dithiocarbamate is synthesized and characterized. Its capability to act as both a photoiniferter reversible addition fragmentation chain transfer agent for the polymerization of styrene examined. Polymerization carried out in bulk under ultra violet irradiation at above 300 nm room temperature shows controlled free radical characteristics up 50% conversions produces well‐defined polymers with molecular weights close those predicted from theory relatively narrow...
Polymerization-induced self-assembly (PISA) is an easily applied synthetic technique for the preparation of polymer nanoparticles with various shapes and at high concentrations.
Functional hairy poly(styrene-b-glycidylmethacrylate) (P(S-GMA)) brushes were generated by grafting from bromoacetylated poly(styrene-divinylbenzene) (P(S-DVB)) microspheres via surface-initiated atom transfer radical polymerization (SI-ATRP). Two different approaches for the covalent immobilization of lipase onto studied first time: (1) direct to polymer their epoxy groups, and (2) glutaraldehyde coupling after attachment a spacer arm (hexamethylendiamine (HMDA)) brushes. The on spacer-arm...
Nitroaromatic explosive detection with high sensitivity and selectivity is requisite for civilian military safety the ecosystem. In this study, aza boron dipyrromethene (aza-BODIPY) dye was selected as a fluorescent-based chemosensor against nitroaromatic compounds (NACs) including 2,4,6-trinitrophenol (picric acid, TNP), 2,4,6-trinitrotoluene (TNT), 2,4-dinitrotoluene (DNT). This molecule exhibits sharp fluorescent behavior quantum yields beyond near-infrared region (NIR) considered...
Abstract A novel method for preparing organosoluble and conducting polyaniline (PANI) is presented. It demonstrated that Cu(II) an excellent catalyst the polymerization of aniline by air oxygen in aqueous emulsions. Reactions carried out at 0 °C or room temperature yield PANIs reasonably high molecular weights (number‐average weight = 23,000–114,000 Da) emeraldine base form are soluble many organic solvents, such as tetrahydrofuran, dimethylformamide, N ‐methylpyrrolidinone, chloroform,...
Fluorescent pyrene-functional poly(divinylbenzene) (PDVB) cross-linked core microspheres were synthesized using the click chemistry strategy as a model study. First, monodisperse prepared by precipitation polymerization 2,2′-azobisisobutronitrile (AIBN) initiator in acetonitrile absence of any stabilizer. Residual double bonds converted to azide-functions hydrobrominated with hydrogen bromide followed azidation NaN3 DMF solution. Propargyl pyrene was independently fluorescent component....
Abstract BACKGROUND: Block copolymers of monomers polymerizing by different mechanisms can be prepared the transformation approach. A wide range combinations polymerization modes has been reported in literature. In this work, approach was further extended to preparation block combining atom transfer radical (ATRP) and photoiniferter processes. RESULTS: Photoactive morpholine‐4‐dithiocarbamate‐terminated polystyrene (MDC‐PS‐MDC) reaction dibrominated polystyrene, obtained ATRP, with...
