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...

[2015][RSC Adv., 2015,5: 6815-6822]Colorless Metallodithiolene Oligomers and Polymers with Intense Near- and Mid-Infrared Absorption
Reported herein are the syntheses and properties of a series of multi-nuclear metallodithiolene complex oligomers (5, 6 and 7) and a homologous polymer (8). The Ni/Pd–dithiolene complexes 5, 6 and 7 are characterized by intense absorption in the spectral region of 1000–1800 nm with a high molar absorption coefficient(e.g.,105M-1cm-1 at 1257 nm for 7). Complex polymer 8 is readily soluble in co...

Radical Graft Polymerization of an Allyl Monomer onto Hydrophilic Polymers and Their Antibacterial Nanofibrous Membranes
Hydrophilic poly (vinyl alcohol-co-ethylene) (PVA-co-PE) copolymers
with 27 mol %, 32 mol % and 44 mol % ethylene were functionalized by
melt radical graft copolymerization with 2,4-diamino-6-diallylamino-1,3,5-triazine
(NDAM) using reactive extrusion. This functionalization imparts antibacterial
properties. The covalent attachments of the NDAMas side chains onto
the PVA-co-PE polymer backbones we...

AngewChem--Design of Aromatic Helical Polymers for STM Visualization: Imaging of Single and Double Helices with a Pattern of pi–pi Stacking
From scanning tunneling microscopy (STM) images of rationally designed helical polymers with a pattern of pi–pi stacking, we successfully identified the single- and double-helical superstructures. The STM images of the helical structures revealed the smallest helical architecture (diameter ca. 1.3 nm) that has been seen so far. Furthermore, the interconversion of single and double helices was fur...
