(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.

(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...

(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.

Water-Soluble Polymers Bearing Phosphorylcholine Group and Other Zwitterionic Groups for Carrying DNA Derivatives
Water-soluble polymers with equal positive and negative charges in the same monomer unit, such as the phosphorylcholine group and other zwitterionic groups, exhibit promising potential in gene delivery with appreciable transfection efficiency, compared with the traditional poly(ethylene glycol)-based polycation–gene complexes. These zwitterionic polymers with various archite...

Hyperbranched polymers meet colloid nanocrystals: a promising av enue to multifunctional, robust nanohybrids
Colloid nanocrystals (NCs) mainly include metal nanocrystals, semiconductor nanocrystals, and insulator nanocrystals, exhibiting interesting size-dependent electrical, optical, magnetic, and chemical properties that cannot be achieved by their bulk counterparts. However, there''s a critical problem that NCs tend to aggregate, which induces degradation of their performance. Hyperbranched polymers (...

Langmuir, 28, 14954–14959: Single-Chain Polymers Achieved from Radical Polymerization under Single-Initiator Conditions
Radical polymerization from a single initiator molecule in a microenvironment is a nearly ideal system in which bimolecular termination, solution concentration, and viscosity changes could be neglected. In this study, we provide two facile methods of preparing polymers via atom-transfer radical polymerization (ATRP) under single-initiator conditions: tether initiators on planar substrates at sup...

[2012][Chem. Commun., 2012, 48, 6426–6428]Near–Infrared Chemiluminescence Tunable from 900 nm to 1700 nm from Narrow–Bandgap Compounds and Polymers
Near-infrared chemiluminescence tunable from 900 nm to 1700 nm was realized from the reaction of the narrow-bandgap compounds andpolymerswithoxalyl chlorideandhydrogen peroxide. A prolonged chemiluminescent process can be achieved in solutions at low temperature or inpolymergels at room temperature.

[2012][Chem. Mater., 2012, 24 (12): 2364–2372]Family of Diazapentalene Chromophores and Narrow-Band-Gap Polymers: Synthesis, Halochromism, Halofluorism, and Visible–Near Infrared Photodetectivity
A family of pyrrolo[3,4-c]pyrrol-1(2H)-one (PPO) and 2,5-diazapentalene (DAP) chromophores and DAP-containing polymers were synthesized, and their optical and electrochemical properties were studied. PPO and DAP chromophores are readily obtained by chemical transformation of the lactam unit in diketopyrrolopyrrole (DPP) dyes and can be used as versatile building blocks for construction of a vari...
