1.Crosslinkable fluorinated poly(aryl ether ketone)s containing pendent phenylethynyl moieties for optical waveguide devices
A type of novel crosslinkable fluorinated poly(aryl ether ketone) containing pendent phenylethynyl moieties (PEP-3F-PEEKn) have been synthesized by copolycondensation reaction of difluoro-monomer with potassium salt of 4-phenylethynylphenyl hydroquinone (PEP-PH) and (3-trifluoromethyl) phenyl hydroquinone 3F-PH). The resulting polymers could be thermally crosslinked at 370 degrees C. The cured pol...

Glucose oxidase-incorporated hydrogel thin film for fast optical glucose detecting under physiological conditions
Hydrogel biosensors usually suffer from a slow response, which severely hinders their practical applications. Here a new optical glucose biosensor was designed, using glucose-sensitive hydrogel films as both glucose-sensing material and Fabry-Perot cavity. The film was fabricated by layer-by-layer assembly from partially oxidized dextran (PO-Dex), chitosan, and glucose oxidase (GOD). The film re...

Optical properties of Si220 nanoclusters from time-dependent density functional theory calculations
The optical properties of bare and hydrogen passivated Si220 nanoclusters(NCs) in four typical motifs(i.e., bulk-like, onion-like, bucky-diamond and icosahedral motifs) were studied via time-dependent density functional theory(TD-DFT) calculations. The calculation results show that there is a significant blue shift in the optical absorption spectra when the Si NCs are passivated with hydrogen. A s...

Facile synthesis of soluble aromatic poly(amide amine)s via C–N coupling reaction: Characterization, thermal, and optical properties
Aromatic poly(amide amine)s (APAAs), as novel highperformance polymers, have been obtained by the condensation polymerization of N,N’-bis(4-bromobenzoyl)-p-phenylenediamine with two different primary aromatic diamines via palladiumcatalyzed aryl amination reaction. The structures of the polymers are characterized by means of FTIR, 1H NMR spectroscopy, and elemental analysis, the results show a ...

Isothermal Crystallization Kinetics Study on Aqueous Solution of Poly (vinyl methyl ether) by FTIR and Optical Microscopy Method
A study on the isothermal crystallization kinetics of aqueous solution of poly (vinyl methyl ether) (PVME) was carried out by Fourier transform infrared (FTIR) and optical microscopy respectively. IR spectra of PVME solution were measured as a function of time under the isothermal crystallization conditions. With the process of crystallization, the phase of solution changes from tra...

Intramolecular charge-transfer emission from conjugated polymer nanoparticles: the terminal group effect on electronic and optical properties
Tuning fluorescence properties and frontier orbital energy levels of hyperbranched conjugated polymer nanoparticles (HCPN-NMe) by the facile introduction of terminal N,N-dimethylaniline groups via an intramolecular charge transfer (ICT) process between the nanoparticle core and the terminal groups was demonstrated for the first time. Compared with the similar hyperbranched conjugated pol...

Temperature-sensitive hydrogel modified by polymerizable liquid crystal AAc-Brij-58: optical and protein adsorption/desorption behaviors
To avoid template-like action of polyoxyethylene 20 cetyl ether (Brij-58) in hydrogel matrix, a polymerizable liquid crystal AAc-Brij-58 based acrylic acid (AAc) and Brij-58, and poly(NIPAm-co-AAc-Brij-58) (ACHX) hydrogels based on N-isopropylacrylamide (NIPAm) and AAc-Brij58 were synthesized by esterification and free-radical polymerization. The chemical structures of resulting ACHX hydroge...

[Reactive and Functional Polymers] Optical bandgaps and fluorescence resonance energy transfer studies of a series of poly(phenyleneethynylene) derivatives
In this paper, research work focuses on the synthesis of a series of PPE-based polymers with commonly used conjugated units, including thiophene, benzo[c][1,2,5]thiadiazole (BT), benzo[c][1,2,5]selenadiazole (BSe), etc. The optical bandgaps of these polymers were tuned in the range of 2.10–2.76 eV. The order of bandgap-lowering ability of these units in PPE-derivatives is: M-3 >&nb...
