POSS-based molecular hybrids with low dielectric constant: Effect of chemical structure and molecular architecture
Three kinds of hybrids with different architectures including dumbbell-type, bead-type, and cross-linked structure, were prepared via the Heck reaction between octavinyl-polyhedral oligomeric silsesquioxane (OV-POSS) and different bromo-substituted aromatic amide monomers. The molecular architecture can be successfully achieved by simply varying the feed ratio of OV-POSS to monome...

(Chemical Science) A calamitic mesogenic near-infrared absorbing croconaine dye/liquid crystalline elastomer composite
In this work, we report the first example of a calamitic mesogenic near-infrared (NIR) absorbing organic dye,
made by functionalizing a thiophene–croconaine chromophore rigid core with two symmetric long flexible
alkyl chains. The liquid crystal (LC) NIR dye YHD796 exhibits a sharp and intense NIR absorption band with
a maximum absorption peak at 796 nm. Taking advantage of the improve...

【Chemical Communications】Facile fabrication of microsphere-polymer brush hierarchically three-dimensional (3d) substrates for immunoassays
Abstract:
We propose a facile UV strategy to construct a hierarchically three-dimensional (3D) substrate that comprises a polystyrene (PS) microsphere layer on the cycloolefin polymer (COP) substrate and densely packed hydrophilic polymer brushes grafting from this 3D backbone. This hierarchical substrate gives a high antibody loading capacity and 3D manner of analyte capture, therefore enhan...

Tailoring the chemical composition and dispersion behavior of fluorinated graphene oxide via CF4 plasma
Grafting fluorine onto graphene oxide (GO) by CF4 plasma treatment was investigated in this study. An easy, low-cost, and effective synthesis of the high-dispersive fluorinated GO (FGO) with tunable atomic ratio of F/O (RF/O) has been realized and the RF/O can be readily manipulated just by adjusting the reaction time. The influence of plasma treatment time on the microstructure, morphology, and d...

Soft Matter, 2011, 7, 8932-8941; Chemical modification of bioinspired superhydrophobic polystyrene surfaces to control cell attachment/proliferation
Surface chemistry is known to have a profound influence on cellular behavior. However, the cells'' responses on surfaces exhibiting extreme wettability values are not yet fully understood. In this work, bioinspired superhydrophobic polystyrene (PS) surfaces were produced by a phase separation method and the in vitro performance of three different cell lines (SaOs-2, L929 and ATDC5) was...

Polymer Chemistry 2015: Real Time Quantification of the Chemical Cross-Link Density of a Hydrogel by in situ UV-vis Spectroscopy
In this paper, we prepare a hydrogel in a green way via the redox reaction between phenol groups and EosinY by visible light irradiation. Eosin Y shows significant absorption at 515 nm while the reduced product does not. A series of control experiments show that almost 100% of the consumed Eosin Y is reacted with phenol groups to form cross-link points. On the basis of the two results, the chemica...

Phys. Chem. Chem. Phys., 2010: The Possible Roles of Water in the Prebiotic Chemical Evolution of DNA
There
is no doubt that water is pivotal to life. Yet, as the emergence of life is
still a big challenge in science, the detailed involvement of water in that
process is not well recognized. Following the clues provided by recent
single-molecule studies on DNA, we attempt to elucidate the possible roles of
water in the prebiotic chemical evolution. Water has been long recognized as an
important rea...

Effect of Chemical Treatments on Transverse Thermal Conductivity of Unidirectional Abaca Fiber/Epoxy Composite
Present paper investigated the effect of mercerization and silane treatments on the transverse thermal
conduction properties of unidirectional abaca fiber–epoxy composite fabricated by resin transfer molding.
As indicated by FTIR, XRD and SEM, the changes in chemical composition, crystalline and lumen
structure of abaca fibers were introduced by chemical treatments. Transverse tensile test showed...

Toward interconnected hierarchical porous structure via chemical depositing organic nano-polyaniline on inorganic carbon scaffold for supercapacitor
In this article, the composites of organic nano-polyaniline (nano-PANI)/interconnected inorganic carbon scaffold (C-scaffold) were prepared via in-situ chemical polymerization. The structures and morphologies were characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR), and the electrochemical behaviors were carried out in 1 M H2SO4 aqueo...
