(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...

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...

Surface treatment of cellulosic paper with starch-based composites reinforced with nanocrystalline cellulose. Industrial & Engineering Chemistry Research
Starch-based composites have become promising materials for eco-friendly packaging applications because of their biodegradability and cost-effectiveness. However, the inherently poor mechanical and barrier properties of starch-based composite films hinder their market potential. Here, nanocrystalline cellulose (NCC) was isolated from cotton cellulose powders using sulfuric acid hydr...

In Situ Forming Hydrogels via Catalyst-Free and Bioorthogonal “Tetrazole–Alkene” Photo-Click Chemistry
In situ forming hydrogels were developed from 4-arm poly(ethylene glycol)?methacrylate (PEG-4-MA) and ?tetrazole (PEG-4-Tet) derivatives through catalyst-free and bioorthogonal “tetrazole?alkene” photo-click chemistry. PEG-4-MA and PEG-4-Tet (Mn = 10 kg/mol) were soluble at 37 °C in phosphate buffer (PB, pH 7.4, 10 mM) at total polymer concentrations ranging from 20 to 60 wt % but formed fluore...

Shape-memory and biocompatibility properties of segmented polyurethanes based on poly( L -lactide) . Frontiers of Chemistry in China, 2007, 2(4): Front. Chem. China 2007, 2(4): 331–336
A series of segmented poly(L-lactide)-polyurethanes (PLA-PUs) were synthesized by a twostep method, with oligo-poly(L-lactide) (PLA) as the soft segments and the reaction product of 2,4-toluene diisocyanate (TDI) and ethylene glycol (EG) as the hard segments. The shape-memory properties and biocompatibility of PLA-PUs
were examined. The 50% compressed PLA-PUs could recover almost 100% to their ori...

Folate-conjugated beta-cyclodextrin from click chemistry strategy and for tumor-targeted drug delivery
To enhance site-speci?c intracellular delivery against the folate receptor, a drug carrier was designed and synthesized by bioconjugation of folic acid (FA) to b-cyclo-dextrins (b-CD) through a poly(ethylene glycol) (PEG) spacer from ‘‘click chemistry’’ strategy. The resulted conjugates were con?rmed by 1H NMR and IR spectroscopy. Host–guest interactions between hydrophobic drug and b-CD are ...
