Polymeric room-temperature phosphorescence (RTP) materials especially multicolor RTP systems hold great promise in concrete applications. A key feature these applications is a triplet charge transfer transition. Aromatic electron donors and acceptors are often essential to ensure persistent RTP. There much interest fabricating non-aromatic charge-transfer-mediated it still remains formidable challenge achieve color-tunable via transfer. Herein, material by embedding quinoline derivatives...

Abstract Flexible temperature sensors often use gels to achieve skin‐inspired softness, but the water evaporation and freezing of hydrogel leakage ionogel, cause unstable signal transmission inaccurate measurement at sub‐zero temperatures. Here steady hypothermic sensing is achieved by designing a supramolecular elastomer containing two types segments: liquid‐free iontronic segment transmit electrical charges prevent ion leakage, neutral with pendant chains damp vibration for stable...

Inhibiting the sintering of Cu-based catalysts for CO2 reverse water–gas shift (RWGS) reaction is still a great challenge. Herein, Cu–Al spinel supported on Al2O3 was prepared by surface solid and used as precursor to obtain Cu particles with high dispersions stabilities. Due cations in spinel, strong chemical interactions between newly generated Al2O3, isolation effects particles, derived from exhibited smaller sizes after H2 reduction, excellent activities, 300 h stabilities RWGS...

Cobalt-based catalysts are promising for converting syngas (CO + H2) into higher alcohols, where Coδ+/Co0 is the active pair alcohol formation. The challenge lies in how to construct and adjust pair. In this work, of can be obtained via interaction between a metal Co nanoparticle (NP) with LaAlO3. A series LaAl1–xCoxO3 (x = 0.2–0.5) were supported on ZrO2 according wet-impregnation method citric acid as complexing agent, after reduction, catalyst Co–LaAlO3/ZrO2 could obtained, cobalt was...

Reduced graphene oxide–epoxy grafted poly(styrene-co-acrylate) composites (GESA) were prepared by anchoring different amount of epoxy modified (EPSA) onto reduced oxide (rGO) sheets through π–π electrostatic attraction. The GESA characterized Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM), and photoelectron (XPS). anti-corrosion properties rGO/EPSA evaluated electro-chemical impedance (EIS)...

Abstract Some marine animals form long‐lived luminescence for predation, communication, camouflage, and anti‐predation. These demonstrate soft nature, sustainable glowing, underwater emission, which are difficult to achieve in synthetic room temperature phosphorescence (RTP) materials. Inspired by these animals, here the study reports RTP hydrogels that show (lifetime >500 ms afterglow >10 s) water. Exceptional mechanical properties simultaneously achieved, including tensile strength...

Metal–organic hybrid materials with long persistent luminescence (LPL) properties have attracted a lot of attention due to their enormous potential for applications in information encryption, anticounterfeiting, and other correlation fields. However, achieving multimodal single component remains significant challenge. Herein, we report two two-dimensional LPL coordination polymers: {[Zn2(BA)2(BIMB)2]·2H2O}n (1) {[Cd(BA)(BIMB)]·3H2O}n (2) (BIMB = 1,3-bis(imidazol-1-yl)benzene; BA butanedioic...
