(Chem.Commun.) Homeotropically-Aligned Main-Chain and Side-on Liquid Crystalline Elastomer Films with High Anisotropic Thermal Conductivities
In this
work, we synthesize nematic main-chain and side-chain
side-on crosslinked liquid
crystalline polymer films (xMELCP and xSSLCP) by in situ photopolymerization of LC thiol-ene monomer T6E5 and LC acrylate monomer A444 oriented by AC electric fields respectively.
The macromolecular main chains are forced to align along the normal directions
of the obtained films,
in order to enhance the ...

[Polym. Chem.] Ultrathin free-standing polymer membranes with chemically responsive luminescence via consecutive photopolymerizations
A facile and general method for the preparation of chemically responsive
polymer films is demonstrated. First, a crosslinked polymer precoating
layer is created via self-initiated photografting and
photopolymerization of ethylene glycol dimethacrylate on a
self-assembled monolayer of a 3-(trimethoxysilyl)propylamine modified
oxidized silicon wafer. The intact methacrylate function...

【Chem Commun】A novel hydrophilic polymer-brush pattern for site-specific capture of blood cells from whole blood
A novel hydrophilic PAMPS–PAAm brush pattern is fabricated to selectively capture blood cells from whole blood. PAMPS brushes provide antifouling surfaces to resist protein and cell adhesion while PAAm brushes effectively entrap targeted proteins for site-specific and cell-type dependent capture of blood cells.

【J Phys Chem Lett】Thickness-Dependent Full-Color Emission Tunability in a Flexible Carbon Dot Ionogel
Multicolor luminescent materials are of immense importance nowadays, while it still constitutes a challenge to achieve luminescence color tunability, transparency, and flexibility at the same time. Here we show how ultrasmall carbon dots (CDs) fluorescing strongly across the visible spectrum can be surface functionalized and incorporated into highly flexible hybrid materials by combination with io...

【Polym Chem】Synthesis of amphiphilic poly(cyclooctene)-graft-poly(ethylene glycol) copolymers via ROMP and its surface properties
Macromonomer cyclooctene-poly(ethylene glycol) (cyclooctene-PEG) was first synthesized before being copolymerized with cyclooctene by ring opening metathesis polymerization (ROMP) to obtain an amphiphilic graft copolymer (poly(cyclooctene)-g-PEG) with polycyclooctene as the hydrophobic trunk chain and PEG as hydrophilic side chains. The structure of poly(cyclooctene)-g-PEG copolymer was characteri...

[Sensor Actuat B-Chem] Aggregation-induced emission of tetraphenylethylene-modified polyethyleneimine for highly selective CO2 detection
A polymer-based visible and quantitative
fluorometric assay for CO2 gas is
constructed using branched polyethyleneimine (PEI) covalently modified
with tetraphenylethylene
(TPE). The sensing mechanism relies on the reaction
of CO2 with
alkylamines of PEI
to induce the “solution-to-precipitation” phase transition of the sensory
polymer (TPE-PEI), thus resulting in strong aggregation-induced fluo...

Several π-conjugated compounds based on diketopyrrolopyrrole and trithiophene substituted with different end groups (alkyl, alkyloxy, and alkylthio) were designed and synthesized for investigation of the material properties and photodetector performance brought by subtle changes in the end groups. Among all, compound 4 with hexylthio groups exhibits the most red-shifted absorption, strongest mo...

[Chem. Commun] Reversible morphology transitions of supramolecular polymer self-assemblies for switch-controlled drug release
A novel method for switch-controlled drug release was developed through the reversible morphology transitions of supramolecular branched copolymer self-assemblies. The reversible transitions from vesicles to nanoparticles were successfully achieved by alternating UV and visible light irradiation to obtain morphology-controlled drug release in a switch mode.
In this st...

[Polym. Chem.] Wafer-scale Synthesis of Defined Polymer Brushes under Ambient Conditions
A method is presented that allows for the first time the preparation of highly defined polymer brush coatings on the wafer-scale under ambient conditions (room temperature, exposure to air) from a broad variety of monomers. The discovered high oxygen-tolerance of the surface-initiated Cu(0)-mediated controlled radical polymerization (SI-CuCRP) yields entire wafers homogeneously covered by a polyme...

Chem. Commum, 2005, 1723-1725. Control over the responsive wettability of poly (N–isopropylacrylamide) film in a large extent by introducing an irresponsive molecule,
An irresponsive but very hydrophobic molecule—fluoroalkylsilane—can be used to cooperate with PNIPAAm to obtain tunable and enhancedly responsive wettability, and thus largely extend the application scope of PNIPAAm film.
