Abstract Excitation wavelength dependent (Ex‐De) emission materials have potential applications in anti‐counterfeiting labels and bioimaging. Nevertheless, few purely organic chromophores are used these areas. In this study, multiple excited states were incorporated into a molecule that was state intramolecular proton transfer (ESIPT) active, with the goal of manipulating relaxation pathways states. The triazole derivative exhibits Ex‐De photoluminescence (PL), maximum PL is located at 526...
A donor–acceptor (D–A) cruciform conjugated luminophore DMCS-TPA was designed and synthesized. The solid shows both aggregation induced emission (AIE) effect high contrast mechanochromic (MC) behavior with a remarkable spectral shift of 87 nm. obvious fluorescence switching from yellowish green to orange can be realized by pressing at only 10 MPa or simply grinding. photophysical properties, theory calculation XPS results demonstrate that the extension conjugation length subsequent...
Modulation of luminescent color or intensity by varying external stimuli, such as temperature, light, ion concentration, etc., has received increasing attention recently because numerous applications sensors, bioanalysis, optical imaging and memories. For instance, electrically induced switching — electroluminochromism (ELC) is one the most powerful promising approaches to implement controllable emission due its facile precise operation. Recent years have witnessed significant advances in...

Cruciform D-A π-architecture is proposed as a platform for constructing bifunctional optoelectronic materials, in which the ICT from donor axis to acceptor can be finely tuned regulate mechanochromic and electrochromic properties.
Electrofluorochromic (EFC) materials, which exhibit electrochemically controllable fluorescence, hold great promise in optoelectronic devices and biological analysis. Here we design such donor-acceptor (D-A) conjugated polymers-P(TPACO) P(TCEC)-that contain the same electron-rich oxidizable polytriphenylamine (PTPA) as π-backbone, yet with different electron-deficient ketone cyano units pendant groups, respectively. They both solvatochromic effects due to intrinsic characteristics of...
A novel colorimetric nanosensor based on stable aggregation of gold nanoparticle (AuNP) triggered by carbon quantum dots (CDs) has been developed for detection Ag+ ions in the presence glutathione (GSH). First, is constructed assembling "shell" surface (AuNP), resulting generation CDs/AuNP. The solution color changes from red to blue. In absence target, addition GSH into aggregated CDs/AuNP exhibits dispersion state corresponding change blue red, because can prefer binding with AuNP...
Abstract Near‐infrared piezochromic materials (PCMs), which show a fluorescence response with clear color difference and strong penetrability, have important potential applications, but few such organic luminophores been reported. High‐brightness donor (D)–acceptor (A) present great for preparing near‐IR PCMs differences. However, the intermolecular π–π interactions are sharply enhanced at high pressures, is not beneficial improvement of properties. Herein, two crystalline polymorphs (TPEB‐α...
Abstract Electrochemiluminescence (ECL) is a means of converting electrical energy into radiative energy. With combined advantages chemiluminescence and electrochemical control, an interest in ECL has grown rapidly broadly applied biological analysis. Recently, nanomaterials have been widely the vast majority studies to remarkably amplify signals, owing their excellent conductivity, large surface area, sometimes catalytic activity. Herein, we present Review article on novel sensors. We...
Abstract Near‐infrared piezochromic materials presenting fluorescence responses with clear color differences and good penetrability have important potential applications, but a few such organic compounds are developed. Twisted intramolecular charge transfer (TICT) emission is versatile in solutions, especially for preparing bio/chem‐sensing due to the excellent sensitivity of alterations external environment. By analogy, solid‐state TICT‐emissive chromophores probably candidates...

Hollow microspheres with multilayered porous shells are formed by a template-free method hierarchical assembly of azithromycin molecules. This simple, rapid, and high-yielding allows the number layers to be tailored regulating initial concentration solution. Such structures may find applications in controlled drug delivery amongst other fields.
