[Analytical Chemistry] Flexible and Adhesive SERS Active Tape for Rapid Detection of Pesticide Residues in Fruits and Vegetables
The efficient extraction of targets from complex surfaces is vital for technological
applications ranging from environmental pollutant monitoring to analysis of explosive
traces and pesticide residues. In our present study, we proposed a
proof-of-concept surface enhance Raman scattering (SERS) active substrate
serving directly to the rapid extraction and detection of target molecules. The
novel su...

Synthesis and Characterization of Comb-like Methoxy Polyethylene Glycol-grafted Polyurethanes via ‘Click’ Chemistry
In this study, a series of comb-likemethoxy polyethylene glycol (MPEG)functionalized polyurethanes (PUs) (PU–g–MPEG)were successfully prepared via ‘click’ chemistry and polyaddition reaction. The copper catalyzed Huisgen 1,3-dipolar cycloaddition was firstly
carried out between 3,5-bis(hydroxymethyl)-1-propargyloxybenzene (PBM) and methoxy polyethylene glycol azide (MPEG–N3) to obta...

Synthesis of an Amphiphilic Brush Copolymer by a Highly Efficient “Grafting onto” Approach via CO2 Chemistry
A novel and robust route for the synthesis of a new amphiphilic brush copolymer, poly(glycidyl methacrylate)-graft-polyethylene glycol (PGMA- g -PEG), with high grafting densities of 97%–98% through a “grafting onto” method via carbon dioxide chemistry is reported. PGMAg-PEG can self-assemble and form stable spherical core–shell micelles in aqueous solution. Besides, the obtained P...

(Chem. Commun.) Near-Infrared-Responsive Gold Nanorod/Liquid Crystalline Elastomer Composites Prepared by Sequential Thiol-Click Chemistry
A
novel NIR-responsive GNR/LCE composite fiber material is prepared by a
three-step sequential thiol-click chemistry approach. Taking advantage of GNRs’
significant photo-thermal effect, GNR/LCE composite material with a very low Au
loading-level (0.09 wt%), under 808 nm NIR stimulus can achieve the N-to-I transition
and shrink dramatically in ambient environment.

(Macromolecules) Polysiloxane-Based Liquid Crystalline Polymers and Elastomers Prepared by Thiol-Ene Chemistry
A series
of side-chain liquid crystalline polymers (LCPs) with polysiloxane backbones
have been synthesized by grafting mesogenic monomers to
poly[3-mercaptopropylmethylsiloxane] (PMMS) via thiol-ene click chemistry. Moreover, by controlling the molar ratio of PMMS and
mesogenic monomers, PMMS-based LCPs can be
partially functionalized, meanwhile leaving spare mercapto groups, which can be
fu...

(JPS Part A) Thermo-Sensitive Electrospun Fibers Prepared by a Sequential Thiol-Ene Click Chemistry Approach
This manuscript describes a straightforward method
to prepare stimuli-responsive fibers by the combined technology of
electrospinning and two facile thiol-ene click chemistry processes:
photo-initialized thiol-ene radical addition and thiol-Michael nucleophilic
addition.

High-efficiency grafting of halloysite nanotubes by using p-conjugated polyfluorenes via ‘‘click’’ chemistry
New hybrid halloysite nanotubes (HNTs) were
obtained by grafting conjugated polyfluorenes (PFs) onto
the surface via ‘‘click’’ chemistry. The hybrid material can
be dispersed in organic solvent such as dichloromethane,
and exhibits intense blue emission peaked at 448 nm. The
absorption and emission spectra of the HNTs show distinct
bathochromic shifts compared to PFs, which can be attributed
t...

Polymer Chemistry 2015: Real Time Quantification of the Chemical Cross-Link Density of a Hydrogel by in situ UV-vis Spectroscopy
In this paper, we prepare a hydrogel in a green way via the redox reaction between phenol groups and EosinY by visible light irradiation. Eosin Y shows significant absorption at 515 nm while the reduced product does not. A series of control experiments show that almost 100% of the consumed Eosin Y is reacted with phenol groups to form cross-link points. On the basis of the two results, the chemica...

Facile functionalization of multilayer fullerenes (carbon nano-onions) by nitrene chemistry and “grafting from” strategy
Facile functionalization of multilayer fullerenes (carbon nano-onions, CNOs) was carried out by [2+ 1] cycloaddition of nitrenes. The products were further derivatized by using the "grafting from" strategy of in situ ring-opening polymerization (ROP) and atom transfer radical polymerization (ATRP). Using one-step nitrene chemistry with high-energy reagents, such as azidoethanol and azidoethyl 2-br...

Construction of Macroscopic Cytomimetic Vesicle Aggregates Based on Click Chemistry: Controllable Vesicle Fusion and Phase Separation
Vesicle–vesicle aggregation to mimic cell–cell aggregation has attracted much attention. Here, hyperbranched polymer vesicles (branched-polymersomes, BPs) with a cell-like size were selected as model membranes, and the vesicle aggregation process, triggered by click chemistry of the copper-catalysed azide-alkyne cycloaddition reaction, was systematically studied. For this purpose, azide and al...
