An efficient synthesis of 3-pyrrolylBODIPY dyes has been developed from a rational mixture various aromatic aldehydes and pyrrole in straightforward condensation reaction, followed by situ successively oxidative nucleophilic substitution using one-pot strategy. These resultant 3-pyrrolylBODIPYs without blocking substituents not only exhibit the finely tunable photophysical properties induced flexible meso-aryl but also serve as valuable synthetic framework for further selective...

Abstract N ‐carboxymethyl chitosans ( ‐CMC) were synthesized from chitosan in water with chloroacetic acid instead of comparatively expensive glyoxylic acid. The optimal reaction conditions 90°C and 4 h a ratio to 5 : 1(w/w). degree substitution product exceeded 1.32. characterized by XRD, FTIR, 1 H‐NMR, the solubility isoelectric point ‐CMC different degrees determined. FTIR H‐NMR data has confirmed that occurred on amino groups. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Abstract A cross-linked chitosan-PVA spherical hydrogel (CSH) was synthesized and its structure characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) X-ray diffraction (XRD). The physical chemical properties of CSH, such as acid resistance swelling, were determined. Finally, Cu(II) ion removal the CSH investigated, effects experimental parameters, including pH, adsorption time, regeneration performance examined. Results revealed that has...
Covalent adaptable networks (CANs) are an emerging kind of smart materials in which cross-links reversible upon some stimuli and then provide malleability a stimuli-responsive ability to the materials. There is trend endow CANs with multistimuli-responsive capabilities rapid stress relaxation pursue more advanced applications. To integrate these two features into one material, here, dual-dynamic covalent bonds (imines boronic esters) aniline trimer (ACAT) were incorporated styrene butadiene...
Different-sized thornball-like In 2 S 3 were synthesized by environmentally-friendly method, which displayed excellent photodegradation of cationic dyes originating from their strong attraction.
Superparamagnetic iron oxide nanoparticles encapsulated in hydrophilic chitosan nanospheres were prepared by nonsolvent-aided counterion complexation completely an aqueous solution. The T2 relaxation of these hybrid vitro and vivo was investigated. It found that the molar transverse relaxivity rate r2 highly depends upon payload within nanospheres. Compared to free nanoparticles, rate, shows approximately 8-fold increase reaches maximum 533 Fe mM-1 s-1. Such a high value is probably...
Random lasers (RLs), which possess peculiar advantages (e.g., emission and coherence tunable) over traditional with optical resonators, have witnessed rapid development in the past decades. However, it is still a challenge to tune lasing peak of an RL wide range. Here, temperature-dependent Förster resonance energy transfer (FRET) demonstrated pyrromethene 597 (PM597, “donor”) Nile blue (NB, “acceptor”) doped chiral liquid crystals. By changing temperature that drives crystal bandgap shift,...
Upconversion nanophosphors (UCNPs) are extremely useful for analytical applications, since they display a high signal-to-noise ratio, and their photobleaching can be ignored. Herein, novel upconversion nanocomposite composed of β-cyclodextrin (β-CD) derivative modified UCNPs rhodamine B (RB) was prepared the detection cholesterol (Cho). The luminescence (UCL) emission serve as Cho-sensing signal by an effective fluorescence resonance energy transfer (FRET) process, using donor RB quencher....

Schematic illustration of the structure, polymerization and multi-stimuli-induced chromatic transition a novel polydiacetylene (PDA)-based supramolecular gel.
Most pyridine-imine Ni(II) and Pd(II) catalysts tend to yield low-molecular-weight polyethylene ethylene-based copolymers in olefin insertion polymerization, as the unilateral axial steric structure of such complexes often cannot provide effective shielding metal center.
