Stimuli‐responsive colorimetric polydiacetylene sensor in polar organic solvent

Chaoqun Ma, Li Hu, Li Jiang, Wenyan Huang, more

Journal of Applied Polymer Science > 141 > 7 > n/a - n/a

Polydiacetylene (PDA) has been actively employed as sensing vehicles owing to its unique colorimetric feature upon environmental stimulation. Here, blue phase PDA has been constructed by topological polymerization of commercial diacetylene acid (DA) noncovalently modified by guest amines. Specifically, PDA including 1‐naphthylmethylamine noncovalently bonded on both sides exhibits long‐term stability...

Self‐Catalyzed Hydroxyl‐Yne Click Reaction: A Powerful Tool toward Red‐Emitting Nontraditional Small Organic Luminogens

Qimin Jiang, Hongyan Zhang, Lingyue Shi, Shuyi Guan, more

European Journal of Organic Chemistry > 26 > 8 > n/a - n/a

Nontraditional small organic luminogens (NTSOLs) without classic conjugated chromophores have attracted significant attention. However, the design and synthesis of NTSOLs with fluorescence in the red region remain significantly challenging. In this study, we established a self‐catalyzed hydroxyl‐yne click reaction for preparing long‐wavelength and red‐emitting NTSOLs. Owing to their perfect reaction...

Anionic Hybrid Copolymerization of Cyclic and Vinyl Monomers without Transesterification

Hongjun Yang, Kaifeng Feng, Yiye Song, Wenyan Huang, more

Macromolecular Chemistry and Physics > 224 > 3 > n/a - n/a

Anionic hybrid copolymerization (AHcP) of cyclic and vinyl monomers provides a powerful strategy to synthesize biodegradable heteropolymers. However, transesterification between comonomeric units often happens making the mechanism complex. Here, AHcP of N,N‐dimethylacrylamide (DMA) with ε‐caprolactone (CL) is investigated at 25 °C, where DMA does not have ester group so that no transesterification...

Precisely Tailoring and Renewing Polymers: An Efficient Strategy for Polymer Recycling

Hongxin Yao, Yongkang Zuo, Yiye Song, Wenyan Huang, more

Macromolecular Chemistry and Physics > 223 > 19 > n/a - n/a

Plastic wastes have contaminated both land and ocean environments throughout the world and hence, it is urgent to explore feasible yet cost‐effective recycling and reuse strategies for plastic wastes in order to solve this menacing problem. The so‐called “back‐to‐oligomer” chemical recycling process may be an efficient and affordable strategy to solve this global issue. However, structural control...

Preparation and characterization of thermal‐ and light‐triggered self‐healing azobenzene polymer

Xiaoqiang Xue, Kang Liang, Xuezi Wang, Wenyan Huang, more

Polymers for Advanced Technologies > 33 > 4 > 1328 - 1340

Both temperature‐ and light‐triggered self‐healing azobenzene polymer was successfully synthesized via radical copolymerization of 4‐(furan‐maleimide ethyl) methyl methacrylate (MMA‐FMI), 4′‐(oxyhexyl methacrylate)‐4‐(oxyfuran‐2‐carbomethoxy) azobenzene (MMA‐FAzo) and 6‐(4′‐methoxy‐4‐oxyazobenzene)‐hexyl methacrylate at 50°C. The structure of the polymer was characterized by proton nuclear magnetic...

Copolymerize Conventional Vinyl Monomers to Degradable and Water‐Soluble Copolymers with a Fluorescence Property

Hongjun Yang, Jiadong Zhang, Yiye Song, Li Jiang, more

Macromolecular Chemistry and Physics > 222 > 1 > n/a - n/a

In the copolymerization of acrylamide (Am) and hydroxyethyl acrylate (HEA), the initial product is a carbon chain polymer with hydroxyl and amide side groups. However, in the present work, these two conventional vinyl monomers are combined into a degradable heterochain copolymer by using a phosphazene base, t‐BuP₄, as a catalyst. NMR not only confirms that the backbone of the resulting copolymer is...

Initiation and Termination in Styrene Free‐Radical Polymerization Initiated by Redox Initiation

Hongfei Han, Jianhan Li, Wenyan Huang, Qimin Jiang, more

Macromolecular Chemistry and Physics > 221 > 22 > n/a - n/a

Hydrogen peroxide and hydroperoxides with substituents of different size are combined with ferrous sulfate to form redox initiation systems, which are used to initiate the polymerization of styrene in emulsion. Gas chromatography and size‐exclusion chromatography are used to measure the monomer conversion and the molecular weight of the polystyrene. Nuclear magnetic resonance is used to identify the...

Anionic Hybrid Copolymerization via Concurrent Oxa‐Michael Addition and Ring‐Opening Polymerizations

Hongjun Yang, Jiadong Zhang, Yongkang Zuo, Yiye Song, more

Macromolecular Chemistry and Physics > 220 > 13 > n/a - n/a

Here, a new type of anionic hybrid copolymerization is exploited via the concurrent oxa‐Michael addition of ethylene glycol and neopentyl glycol diacrylate and the ring‐opening polymerization of ε‐caprolactone. The hybrid copolymerization process and the resulting copolymers are characterized using nuclear magnetic resonance, size exclusion chromatography, differential scanning calorimetry measurements,...

Supramolecular host-guest polycationic gene delivery system based on poly(cyclodextrin) and azobenzene-terminated polycations

Qimin Jiang, Yunti Zhang, Renxi Zhuo, Xulin Jiang

Colloids and Surfaces B: Biointerfaces > 2016 > 147 > C > 25-35

This article describes the supramolecular host-guest polycationic gene delivery system based on poly(β-cyclodextrin) (PCD) and azobenzene-terminated polycations. The azobenzene-terminated linear (Az-LPDM) and branched (Az-BPDM) cationic polymers were synthesized by atom transfer radical polymerization (ATRP) of 2-dimethylamino ethyl methacrylate (DMAEMA). The formation and photosensitive behavior...
