J. Am. Chem. Soc. 2006: Weakly bound water molecules shorten single-stranded DNA
In this paper, we measure
the single chain elasticity of an oligomer ssDNA in both aqueous and
non-aqueous, apolar liquid environments by AFM-based single molecule force
spectroscopy. We find a marked deviation between the force-extension relations
recorded in the two ambients. This difference is attributed to the additional
energy required to break the H-bond directed water bridges around ssDNA c...

J. Am. Chem. Soc. 2007: Double Stranded DNA Dissociates into Single Strands when Dragged into a Poor Solvent
DNA displays a richness of biologically relevant
supramolecular structures, which depend on both sequence and ambient. The effect of dragging
dsDNA from water into poor solvent on the double-stranded structure is still
unclear because of condensation. Here
we employ single molecule techniques based on atomic force microscopy and molecular dynamics (MD) simulations to investigate the change in...

[Chem. Commun.] Chiral recognition of L-tryptophan with beta-cyclodextrin-modified biomimetic single nanochannel
A stable system of enantioselectively recognising L-tryptophan based on
b-cyclodextrin-modified single nanochannel fabricated in a polyimide
membrane was demonstrated, and we realized the chiral recognition of
an essential amino acid with this system for the first time.

[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...

[2014][J. Mater. Chem. C, 2014,2: 2431-2438]Panchromatic Small Molecules for UV-Vis-NIR Photodetectors with High Detectivity
Two donor–acceptor–donor (D–A–D) type low-bandgap small molecules, M1 and M2, with bis(2-thienyl)-N-alkylpyrrole (TPT) as the donor and thieno[3,4-b]thiadiazole (TT) as the acceptor were designed and synthesized. The absorption, transmission, electrochemical, thermal and film properties were studied. The compounds showed panchromatic absorption in the spectral range of 300–1000 nm. Moreover...

[Polym. Chem.] Morphology transitions of supramolecular hyperbranched polymers induced by double supramolecular driving forces
Tuning the morphology of supramolecular hyperbranched polymers (SHPs) in solution has theoretical and practical significance in SHP applications. This study successfully achieved SHP morphology transitions from branched supramolecular structures to spherical nanosized micelles in mixed solvents. Transmission electron microscopy, dynamic light scattering, 2D 1H NMR ROESY, and fluor...

[Chem. Commun.] A supramolecular hyperbranched polymer based on molecular recognition between benzo-21-crown-7 and secondary ammonium salt
A novel A2-B3-type supramolecular hyperbranched polymer was prepared based on the benzo-21-crown-7/secondary ammonium salt recognition motif. The resulting supramolecular polymer exhibited a reversible disassembled–assembled process by adding or removing potassium ions.

[Beilstein J. Org. Chem.] Linear-g-hyperbranched and cyclodextrin-based amphiphilic block copolymer as a multifunctional nanocarrier
In this paper, a novel, multifunctional polymer nanocarrier was designed to provide adequate volume for high drug loading, to afford a multiregion encapsulation ability, and to achieve controlled drug release. An amphiphilic, triblock polymer (ABC) with hyperbranched polycarbonsilane (HBPCSi) and β-cyclodextrin (β-CD) moieties were first synthesized by the combination of a twostep&nb...

JMolCat-Chem--A study of biomimetic system: Exploration of factors modulating the catalytic capacity of glutathione peroxidase mimics
A cyclodextrin-based artificial glutathione peroxidase (GPx) system, which was designed to carry single or double binding sites, has been investigated by observing the recognition features of these mimics. The GPx mimics exhibited high catalytic activities mainly due to the substrate recognition generated by hydrophobic driving force. The different recognition mechanisms led to quite different cat...
