[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.

Chem. J. Chinese Universities, 2002, 23, 1778-1780. Direct Fabrication of Magnetite Nanoparticles Patterns via“Dip-Pen”Nanolithography
We use 8 nm magnetite nanoparticles as "ink", self assembly monolayer(SAM) of
bovine serum albumin(BSA) as "paper" to generate arbitrary structures at micro
or nanometer scales in the DPNprocedure. AFMand LFMare used to image the
patterns. The height profile of pattern is about 8 nm, which is consistent with
the diameter of magnetite nanoparticles. It means that the magnetic monolayer
pattern...

(Polym. Chem.) Poly(Vinyl Benzoate)-Backbone Mesogen-Jacketed Liquid Crystalline Polymers
Previously reported polymer backbone structures of mesogen-jacketed liquid crystalline polymers
(MJLCPs) are still limited to polyacrylate, polystyrene, polyacetylene, polysiloxane, polythiophene and
polynorbornene. In this manuscript, we describe a new system of MJLCPs with poly(vinyl benzoate)-
backbone (PVBnB), which were synthesized by solution polymerization and bulk photo-polym...

(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.

(Polym. Chem.) Side Chain Liquid Crystalline Polymers with an Optically Active Polynorbornene Backbone and Achiral Mesogenic Side Groups
This work describes series of side-on and end-on SCLCPs with an
optically active polynorbornene main chain and achiral mesogens. The side-on SCLCPs display the tendency of forming nematic,
i.e. achiral mesophases, in strong contrast with the chiral nematic phase exhibited by their comparative end-on analogues.

(J. Mater. Chem. C) Mesogen-Jacketed Liquid Crystalline Polymers and Elastomers Bearing Polynorbornene Backbone
This
manuscript describes a series of mesogen-jacketed liquid crystalline polymers
(MJLCPs) and elastomers (MJLCEs) bearing a novel polynorbornene backbone, onto
which the liquid crystalline mesogen is laterally attached by a single covalent
bond without spacers.
