ConspectusSelf-assembled nanomaterials show potential high efficiency as theranostic agents for high-performance imaging and therapy. However, superstructures properties of preassembled are somewhat compromised under complicated physiological conditions. Given the advantages dynamic nature adaptive behavior self-assembly systems, we propose an "in vivo self-assembly" strategy in situ construction living objects. For proof-of-concept study self-assembly, developed a bispyrene (BP) molecule...
We report an assembly and transformation process of a supramolecular module, BP-KLVFF-RGD (BKR) in solution on specific living cell surfaces for imaging treatment. The BKR self-assembled into nanoparticles, which further transformed nanofibers situ induced by coordination with Ca2+ ions.
Abstract For the first time, high‐percentage molybdosilicic acid fiber mats (20–80% H 4 SiMo 12 O 40 ) were prepared using electrospinning technique. The characterized by IR, XRD, and DSC. results indicated that poly(vinyl alcohol) was changed from a semicrystalline to an amorphous state with increasing content. scanning electron microscopy (SEM) showed average diameter of fibers about 285–600 nm. effects viscosity conductivity /poly(vinyl solution on morphologies investigated. swelling...
Abstract A soluble aromatic polyimide was chloromethylated via a reaction with chloromethyl methyl ether in the presence of tin(IV) chloride to produce new starting material for modification polyimides. The chemical structure resulting polymer confirmed by 1 H NMR and Fourier transform infrared spectroscopy. maximum number groups per repeat unit 1.81. stable up 250 °C both chloroform tetrahydrofuran. So that its utilization further could be demonstrated, cinnamic acid reacted formed...
A low-loss, thermally stable TE-mode selective optical waveguide was fabricated using a photosensitive fluorinated polyimide. The polymer undergoes photocrosslinking under UV exposure, thus changing its refractive index. photocrosslinking-induced index change utilized to form channel waveguides. propagation losses of the polyimide waveguides were less than 0.3 and 0.5 dB/cm for TE polarization at wavelengths 1.3 1.55 μm, respectively. measured extinction ratio higher 29 28 dB film remains...
Novel photocrosslinkable sulfonated poly(arylene ether sulfone)s containing chalcone moieties in the polymer backbone (SPAEF) were synthesized from 4,4′-dihydroxychalcone (4DHC), 4,4′-difluoro-diphenylsulfone-3,3′-disulfonate (SDFDPS) and decafluorobiphenyl (DFBP). We introduced a new strategy to crosslink photosensitive electrolyte membranes by UV irradiation swollen state order preserve interconnected hydrophilic channels hydrated SPAEF membrane. Photocrosslinked showed desired effects of...
Graphene oxide (GO)-doped dimethyl sulfate (DMS)/poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) superconductive alignment layer, aligning liquid crystals (LCs) with super switching and non-residual direct current (non-residual DC) performance, is presented in this manuscript. Doping of GO increased the pristine polar energy a thin composite layer as well corresponding anchoring LCs sandwiched between these layers but only slightly affected layers' morphology. When rubbed...
We report a liquid crystal photoalignment material with high photosensitivity and excellent thermal stability. The chloromethylated aromatic polyimide exhibited defect-free homogeneous alignment of crystals upon irradiation polarized deep ultraviolet (UV) for 50s. aligning ability the film was retained up to 210°C, cell containing could be stored at 85°C more than 14 days without any deterioration. FT-IR UV–vis spectra confirmed that induced by photodecomposition polyimide, drastically...
