Electrofluorochromism has attracted great attention due to the intelligence optoelectronic and sensing applications. The intrinsically switchable fluorophores with high solid-state fluorescence are regarded as key for ideal electrofluorochromic materials. Here, we reported an AIE-active polyamide diphenylamine tetraphenylethylene units, showing quantum yield up 69.1% solid polymer film stable electrochemical cycling stability. exhibited reversible color emission switching even in hundreds of...
Porphyrin-graphene composites have attracted increasing attention due to a number of intriguing functions, and their photoelectrical catalytic performances are expected be modulated through different approaches. In the present study, designed polymer based on phenyl sulfone, (p-amino)phenylhydroquinone, symmetrical dinaphthylporphyrin were covalently attached graphene oxide (GO) sheet. The formation nanohybrid was characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD),...

Electrofluorochromic (EFC) materials have gained extensive attention owing to their interesting modulations of fluorescence by an electric stimulus. However, the limited performances, especially low on/off contrast, significantly hampered further applications. Herein, we design a new strategy achieve high-contrast electrofluorochromism combinations "colorless-to-black" electrochromism and highly fluorescent AIE activity. Given effective quenching effect high solid-state fluorescence,...
Actomyosin networks constrict cell area and junctions to alter tissue shape. However, during expansion under mechanical stress, actomyosin are strengthened polarized relax stress. Thus, cells face a conflicting situation between the enhanced contractile properties behaviour of or tissue. To address this paradoxical situation, we study late Drosophila oogenesis reveal an unusual epithelial wave behaviour. Mechanistically, Rac1 Rho1 integrate basal pulsatile with ruffles focal adhesions...
Multiple stimuli-responsive fluorescent materials have gained increasing attention for their fundamental investigation and intelligent applications. In this work, we report design synthesis of a novel polyamic acid bearing oligoaniline, triphenylamine, fluorene groups, which served as sensitive units fluorescence emission unit, respectively. The resulting polymer exhibits multiple switching behavior triggered by redox species, pH, electrochemical, pressure stimuli. Every mechanism upon each...
Electrofluorochromic (EFC) materials have aroused great interest owing to their interesting ability of tuning fluorescence in response the applied potential.

Electrochromic (EC)/electrofluorochromic (EFC) bifunctional materials are receiving great attention because of their promising applications in optoelectronic devices. However, the development ideal EC/EFC is still a challenge poor integration performances (optical contrast, response speed, and switching stability).

Abstract Organic‐hybrid particle‐based materials are increasingly important in (opto)electronics, sensing, and catalysis due to their printability stretchability as well potential for unique synergistic functional effects. However, these properties often limited poor electronic coupling between the organic shell nanoparticle. N ‐heterocyclic carbenes (NHCs) belong most promising anchors achieve delocalization across interface, they form robust highly conductive bonds with metals offer a...
Template-assisted colloidal self-assembly has gained significant attention due to its flexibility and versatility. By precisely controlling the shape of template, it is possible achieve custom-designed nanoparticle assemblies. However, a major challenge remains in fabricating these templates over large areas at low cost. Recently, one-dimensional (1D) nano-wrinkle structures have been effectively used for linear assembly single-chain or multi-chain nanoparticles, which feature abundant...
