This Review provides a comprehensive analysis of recent development in the field aggregation-induced emission (AIE)-active tetraphenylethylene (TPE) luminophores and their applications biomolecular science. It begins with discussion diverse range structural motifs that have found particular sensing, demonstrates TPE structures derivatives been used for analytes such as H+, anions, cations, heavy metals, organic volatiles, toxic gases. Advances are discussed depth where is utilized...
Rigid p-octiphenyl rods were used to create helical tetrameric pi-stacks of blue, red-fluorescent naphthalene diimides that can span lipid bilayer membranes. In vesicles containing quinone as electron acceptors and surrounded by ethylenediaminetetraacetic acid hole acceptors, transmembrane proton gradients arose through reduction upon excitation with visible light. Quantitative ultrafast relatively long-lived charge separation was confirmed the origin photosynthetic activity femtosecond...
The synthesis and characterization of a highly fluorescent core-substituted naphthalene diimide sensor (varphi = 0.34) bearing bis-sulfonamide group is described. compound shows unique selectivity reactivity for the fluoride ion over other anions in CHCl(3) by two-stage deprotonation process leading to colorimetric response. In DMSO solution, shown be selective (K(a) approximately 10(6) M(-1)) with more pronounced changes absorption characteristics.
Core-substituted naphthalenediimides (cNDIs) are rapidly emerging as a powerful strategy to create functional nanomaterials and their implications in biological supramolecular chemistry significant. Recent developments the synthesis of cNDIs have allowed several groups probe function this interesting class dye molecules molecular sense. Core-substitution NDI can be seen an opportunity extend planar, rigid core could used prepare novel structures for applications organic, biosupramolecular...
The development of a novel uncomplicated sensor for sensitive and selective detection in biomedical analysis is necessary. This study demonstrates the preparation nitrogen-doped carbon dots (N-C dots) via hydrothermal synthesis as naked eye fluorescent probe dopamine (DA). successful N-C was confirmed using various microscopic spectroscopic techniques. In addition, N-C-dot-incorporated gel strips were prepared through simple approach dopamine. linear range 2-20 μg/mL with limit low 1.97...
Abstract Precise supramolecular architecture is often essential for significant function. Simple methods to reliably and rapidly demonstrate the existence of such structure function at relevant concentrations in complex systems are badly needed. Hill plots, describing dependence a signal on n ‐th power monomer concentration, compatible only with identification supramolecules that do not really exist, is, endergonic self‐assembly (Litvinchuk et al., J Am Chem Soc 2004;126:10067). Here, we...
This communication describes an infinite 1D ribbon metal–organic framework (MOF) that crystallizes to produce large channels (13.4 × 17.5 Å) and exhibits strong aggregation enhanced fluorescence emission. The network is composed of tetrapyridine tetraphenylethene molecules coordinating ZnCl2 nodes. When activated, the turn-on in response methyl-substituted volatile organic compounds (VOCs) quenching nitro-substituted VOCs. MOF shows potential as a valuable sensor due its high surface area,...
Graphene nanoplates (GNPs) can be used as a platform for homogeneous distribution of adsorbent nanoparticles to improve electron exchange and ion transport heavy-metal adsorption. In this study, we report facile thermal decomposition route fabricate graphene-supported Fe–Mg oxide composite. The prepared composite was characterized using scanning microscopy, transmission energy-dispersive spectrometry, X-ray diffraction, photoelectron spectroscopy. Batch experiments were carried out evaluate...
Through the conjunction of tetraphenylethylene and diketopyrrolopyrrole functionalities, a novel four-directional non-fullerene electron acceptor (denoted as 4D) was designed, synthesized characterized. The new chromophore is highly soluble (for instance >30 mg mL(-1) in o-dichlorobenzene), thermally stable, exhibits energy levels matching those conventional routinely used donor polymer poly(3-hexyl thiophene). A power conversion efficiency 3.86% obtained solution-processable...
The self-assembly of core-substituted naphthalene diimides bearing triethylene glycol motifs leads to the formation stable vesicles in DMSO and CHCl3/MeOH (6 : 4, v/v) solvents. were evaluated by means UV/vis fluorescence spectroscopy, transmission electron microscopy, atomic force microscopy dynamic light scattering.
