Three scandium metal-organic frameworks (Sc-MOFs), [Sc(pydc)(Hpydc)(H2O)]·H2O (1), [Sc2(pydc)3(H2O)4]·5H2O (2) and [Sc(pydc)(H2O)(NO3)] (3) with similar Sc2(pydc)2 building unit were prepared by using 2,3-pyridinedicarboxylic acid (H2pydc) ligand under hydrothermal conditions. Compound 1 exhibits a ladder-shaped chain…
In this study, a novel assay for the detection of free chlorine is proposed for the first time. It is based on a redox reaction that occurs between triangular silver nanoprisms and free chlorine, which results in a morphological transformation and a change of the localized surface plasmon resonance (SPR) of the triang…
We introduce a model for thin films of multicomponent fluids that includes lateral and vertical phase separation, preferential component attraction at both surfaces, and surface roughening. We apply our model to thin films of binary polymer blends, and use simulations of different surface-blend interaction regimes to…
Novel photosensitizers (PSs) with formyl bipyridyl ligands in different positions were developed to improve the electron transfer from an iridium complex PS to a colloidal platinum catalyst, resulting in much higher turnover numbers than the non-formyl bipyridyl Ir-PS in photocatalytic hydrogen generation.
Two novel porphyrin dyads (9 and 11) consisting of two zinc-metallated porphyrin units, covalently linked at their peripheries through 1,2,3-triazole containing bridges and functionalized by a terminal carboxylic acid group, have been synthesized via "click" reactions, which are Cu-catalyzed Huisgen 1,3-dipolar cycloa…
ZnO films were grown by atomic layer deposition at 35 °C on poly(methyl methacrylate) substrates using diethylzinc and water precursors. The film growth, morphology, and crystallinity were studied using Rutherford backscattering spectrometry, time-of-flight elastic recoil detection analysis, atomic force microscopy, s…
Four model thiosemicarbazide anion chemosensors containing three N-H bonds, substituted with phenyl and/or 4-nitrophenyl units, were synthesised and studied for their anion binding abilities with hydroxide, fluoride, acetate, dihydrogen phosphate and chloride. The anion binding properties were studied in DMSO and 9 :…
A novel 4'-(4-(diphenylamino)thienyl)-2,2':6',2''-terpyridine ligand () based on thiophene and its complexes (X = Cl, Br, I, SCN) was designed, synthesized and characterized by elemental analysis, far-IR, MALDI-TOF-MS, and single crystal X-ray diffraction analysis. Structural studies revealed that the central zinc(ii)…
The rich stereochemistry of the self-assembled monolayers (SAMs) of four butanethiols on Au(111) is described, the SAMs containing up to 12 individual C, S, or Au chiral centers per surface unit cell. This is facilitated by synthesis of enantiomerically pure 2-butanethiol (the smallest unsubstituted chiral alkanethiol…
A systematic study on the anion-binding properties of acyclic halogen- and hydrogen-bonding bis-triazolium carbazole receptors is described. The halide-binding potency of halogen-bonding bis-iodotriazolium carbazole receptors was found to be far superior to their hydrogen-bonding bis-triazolium-based analogues. This l…
Inverted organic solar cells based on a small molecule donor and a polymer acceptor were fabricated using a layer by layer solution process, which exhibited a power conversion efficiency up to 1.12%.
Peptides and proteins represent attractive building blocks for the development of new functional materials due to the biocompatibility and biodegradability of many naturally abundant proteins. In nature, sophisticated material functionality is commonly achieved through spatial control of protein localisation and struc…
In this investigation, ultrasonication process was used for the synthesis of magnesium doped nano-hydroxyapatite (MH) (0, 1, 2, and 3 mol% of Mg concentration) particles with controlled size and surface morphology. The size of the prepared MH particles was in the range of 20-100 nm with narrow distribution. Increase i…
A comparative study of the solution self-assembly behavior of two polystyrene- arm -polyisoprene- arm -polyferrocenylsilane (μ-SIF) miktoarm star terpolymers of similar composition has been conducted: one with a short, atactic, noncrystallizable poly(ferrocenylethylmethylsilane) (PFEMS) block (μ-SIF a ) and one with a…
Novel carbazole derivatives are first reported as two-photon photosensitizers for DNA photodamage under near-infrared light exposure.
Thin and ultrathin polymer films combined with nanoparticles (NPs) are of significant interest as they are used in a host of industrial applications. In this paper we describe the stability of such films (hpoly ≤ 30 nm) to dewetting, specifically, how the development of a spinodal instability in a composite NP-polymer…
Novel UCST (upper critical solution temperature) type doubly thermosensitive core–shell nanoparticle gels were prepared in order to investigate swelling behaviors. The core–shell nanoparticle gels are synthesized via precipitation polymerization and are composed of a chemically cross-linked poly(methyl methacrylate) (…
The capability of montmorillonite as a matrix (MONT) to improve the photostability of photolabile drugs has been recently reported. Herein promethazine (PRO), which was chosen as a model drug because of its photodegradation mechanism, was intercalated into this inorganic matrix, and the effects on drug photoprotection…
A protocol for introducing the redox responsive Se–Se bond into well-defined polymer backbones was developed.
Gene therapy has been concerned to be one of the most promising strategies to treat many diseases such as genetic disorders and cancer. However, design of safe and highly efficient gene delivery vectors still remains a great challenge. In this work, we report the use of partially acetylated dendrimer-entrapped gold na…
