[Materials Research Express] Electric Field Induced Structural Color of Fe3O4 and Fe3O4@C nanoparticles and their dielectric spectroscopy
The photonic properties of Fe3O4@C and Fe3O4 colloidal suspensions in an
external electric field have been investigated. Compared to Fe3O4, the Fe3O4@C
colloidal suspension has been found to have a wider tunability range of the
optical spectrum and a stronger electric response in low electric fields. Based on
the dielectric spectroscopy analysis of Fe3O4@C and Fe3O4 colloidal suspensions,
a dielec...

Improvement of dispersion and color effect of organic pigments in polymeric films via microencapsulation by the miniemulsion technique
Three primary pigment/poly(n-butyl acrylate-co-styrene) (P(BA+St)) nanocomposites were prepared via encapsulation of the corresponding organic pigments via the miniemulsion technique. The resulting latexes of the P(BA+St)/pigment nanocomposites were filmed in a PTFE mould or printed onto cotton fabric. The morphology of the P(BA+St)/pigment nanocomposites, and the dispersion of pigment particles i...

[JMCA] Electric Field Induced Structural Color Changes of SiO2@TiO2 Core-Shell Colloidal Suspensions
A new core-shell nano building block of SiO2@TiO2 using high refractive index materials of TiO2 to coat SiO2 colloidal NPs by one step approach was prepared. Through the self-assembly of SiO2@TiO2 core-shell NPs through applied electric field, a suspension of photonic crystals with close packed are formed in propylene carbonate. The reflectance spectrum of the SiO2@TiO2 suspension was investigated...

A fluorescent color/intensity changed chemosensor for Fe3+ by photo-induced electron transfer (PET) inhibition of fluoranthene derivative
A fluorescent color/intensity changed fluoranthene derivative chemosensor for Fe3+ has been prepared and confirmed by 1H-NMR, 13C-NMR, HRMS, and crystal data, which displays a high selectivity and antidisturbance for Fe3+ among environmentally and biologically relevant metal ions. Fluorescence studies show that fluorescent emission peak blue shifts about 100 nm with fluorescent intensity enhancing...

[ACS Appl. Mater. Interfaces] Ligand-Induced Tunable Dual-Color Emission Based on Lead Halide Perovskites for White Light-Emitting Diodes
Cesium lead halide perovskites (CsPbX3, X = Cl, Br, and I) have emerged as an important class of colortunable light-emitting materials in the past 4 years. However, single-CsPbX3 nanostructures with dual-color emission remain scarce. Here, we demonstrate dual-color emission from lead halide perovskite nanowires induced by the surface ligands, that is, oligomeric methoxypolyethylene glycol (MEOPE...

[Macromol. Rapid Commun.] A Color-Tunable Fluorescent Supramolecular Hyperbranched Polymer Constructed by Pillar[5]arene-Based Host–Guest Recognition and Metal Ion Coordination Interaction
Fluorescent supramolecular polymers are an important kind of smart material. In this work, a new fluorescent supramolecular hyperbranched polymer (FSHP) is constructed by orthogonal self-assembly: pillararene-based host–guest interaction and metal ion complexation interaction. The FSHP exhibits concentration-controllable fluorescence emissions. The photoluminescence spectra ...

Genipin-cross-linked silk sericin/polyN-isopropylacrylamide IPN hydrogels: color reaction between silk sericin and genipin, pore shape and thermo-responsibility
To investigate the color reactions between naturally cross-linking agent genipin and silk sericin (SS), a series of genipin/SS film with adjustable color were firstly fabricated and analyzed by FTIR, UV/Vis and colorimetric methods. Then under the various genipin/SS contents, double cross-linked genipin/SS/Poly(N-isopropyl- acrylamide/N,N0-Methylene-bis-acrylamide) (HMGX) hydrogels were prepared, ...

【Polymer】 Cetyl trimethyl ammonium bromide (CTAB) micellar templates directed synthesis of water-dispersible polyaniline rhombic plates with excellent processability and flow-induced color variation
Well-defined PANI rhombic plates are produced via a cetyl trimethyl ammonium bromide (CTAB) micellar soft template route in low acid environment. Lamellar micelles consisting of CTAB and ammonium persulfate (APS) molecules not only serve as both soft templates and oxidant for oxidative polymerization of aniline, but also provide intermolecular interactions to assemble two-dimensional PANI sh...

86. Dual-color polymer light-emitting diodes based on hybrid films of soluble poly(p-phenylenevinylene) derivatives. C.Liu, M.Wang*, M.Wu, T.X.Liu*, G.Y.Zhong, H.B.Yao. Thin Solid Films, 515(20-21), 7930-7934, 2007.
Polymer light-emitting diodes with red and green emissions were fabricated on the same indium-tin oxide (ITO) substrate. The basic device structure is ITO/electroluminescent polymer/Al. The polymer light-emitting layer of the dual-color device fabricated in this work has two parts, one part is the single (poly[2,5-dimethyldodecylsilyl-1,4-phenylenevinylene]) (Si-PPV) film, and the other part consi...
