ConspectusStimuli-responsive materials have a great potential in various novel photoelectric devices, such as self-adaptive adjustment intelligent detection, molecular computers with information storage capability, camouflage and anticounterfeiting display, energy-saving displays, others. However, progress related areas has been relatively slow because of the lack high-performance smart limitations available reaction mechanisms currently. To address these problems fundamentally, new need to...
Advances in the development of fluorescent carbon dots (CDs) for detecting nitro-explosives have attracted great interest. However, developing long-wavelength luminescence CDs highly selective determination 2,4,6-trinitrophenol (TNP) and getting insight into detection mechanism remain further to be investigated. Here, excitation-independent yellow-green emission with good photostability low biotoxicity were introduced TNP selectively. Then, two types electron transfer (ET) processes...
Abstract Bistable display has been a long-awaited goal due to its zero energy cost when maintaining colored or colorless state and electrochromic material highly considered as potential way achieve bistable simple structure possible manipulation. However, it is extremely challenging with insurmountable technical barriers related traditional mechanisms. Herein prototype for electronic billboard reader high efficiency demonstrated excellent bistability (decay 7% in an hour), reversibility (10...
Control of stereochemistry plays a key role in medicinal chemistry, material and life science. As prominent AIE luminogen, tetraphenylethene (TPE) derivatives have E/Z isomers which are challenging to separate even by HPLC. Herein, we designed oxetane-substituted TPE (TPE-2OXE) separated pure simple column chromatography with high yields, as confirmed mass spectrometry, IR NMR spectroscopy. The isomerization the two can occur photo- thermo-activation. Importantly, (Z)-TPE-2OXE isomer solid...
RGB color-tunable "turn-on" electrofluorochromic (EFC) devices with high color purity (457 nm for blue, 539 green, and 641 red), relatively quick response/fading speeds remarkable fluorescence contrast ratios are successfully fabricated. They exhibit great potential increasingly important multistage encrypted information storage displays.
High-contrast fluorescence switching has been achieved in polymer films or fibers with non-invasive stimuli.
With the rapid development of human society, consumer electronics have brought marvelous changes to daily life, but they are accompanied by much higher demand display quality and visual experience. Therefore, ideal conversion among three primary colors-red (R), green (G), blue (B)-in a single pixel has been better way avoid insurmountable technical barrier subpixel technology modern displays. Electrofluorochromic (EFC) materials capable novel luminescent switching, open powerful design...
Bistable electrochromic materials are a promising alternative solution to reduce energy consumption in displays. Limited by the mechanism and lack of design strategy, only few have truly been able achieve bistability. Herein, novel strategy is proposed bistable based on polymer-assisted dynamic metal-ligand coordination. The such unconventional systems proved sufficient characterization. Synergistic stabilization polymerized switchable dyes ionic ligand polymer attracted each other...

Here we discuss methods, challenges, opportunities for implementing in terms molecular design, device structure, further expansion, required criteria, hopefully benefiting the light-related community.
Transparent non-emissive displays are ideal for augmented reality (AR) applications due to their ability modulate ambient light as colored and transparent pixels. Electrochromic (EC) with "ON" "OFF" states can help enable such a display. However, unwanted image diffusion signal crosstalk the imbalance between performance preparation process limit practical application. In this work, we present energy-efficient EC display prototype (4.2 inch, 16 × pixels). We minimize problem by exploiting...
Multicolor organic electrochromic materials are important for the generation of full-color devices. However, achieving multiple colors using a single-molecule material has proved challenging.
