Abstract Ultralong organic phosphorescence (UOP) has attracted increasing attention due to its potential applications in optoelectronics, bioelectronics, and security protection. However, achieving UOP with high quantum efficiency (QE) over 20 % is still full of challenges intersystem crossing (ISC) fast non‐radiative transitions molecules. Here, we present a novel strategy enhance the QE materials by modulating intramolecular halogen bonding via structural isomerism. The CzS2Br reaches up...
Abstract Persistent luminescence from purely organic materials is basically triggered by light and electricity, which largely confines its practical applications. A AIEgen exhibits not only persistent photoluminescence, but also transient room‐temperature mechanoluminescence. By simply turning on off a UV lamp, tricolor emission switching between blue, white, yellow was achieved. The data single‐crystal structure analysis theoretical calculation suggest that mechanism of the observed...
Two heavy atom-free white-light emitting luminophores exhibit fluorescence–phosphorescence dual-emission and are multi-stimuli responsive at room temperature.
Abstract Soft luminescent materials are attractive for optoelectronic applications, however, switching dominant chromophores property enrichment remains a challenge. Herein, we report the first case of soft organic molecule (DOS) featuring selective expression chromophores. In response to various external stimuli, different DOS can take turns working through conformation changes, exhibiting full‐colour emissions peaking from 469 nm 583 ten individual single crystals. Dynamic triplet‐exciton...
Magnetic miniature soft robots have shown great potential for facilitating biomedical applications by minimizing invasiveness and possible physical damage. However, researchers mainly focused on fixed-size robots, with their active locomotion accessible only when the cross-sectional dimension of these confined spaces is comparable to that robot. Here, we realize scale-reconfigurable ferrofluidic (SMFRs) based ferrofluid droplets propose a series control strategies reconfiguring SMFR's scale...
Abstract Organic ultra‐long room‐temperature phosphorescence (RTP) materials in the amorphous state have attracted widespread attention due to their simple preparation and flexibility adopt various forms sensors, bioimaging, encryption applications. However, molecular host for host–guest RTP systems is highly demanded but limited. Here, a universal (DPOBP−Br) has been designed by integration of an moiety diphenylphosphine oxide (DPO) intersystem crossing (ISC) group 4‐bromo‐benzophenone...
Electrodes with three-dimensional (3D) nanostructure are expected to improve the energy and power densities per footprint area of lithium ion microbatteries. Herein, we report a large-scale synthesis SnO2/α-Fe2O3 composite nanotube array on stainless steel substrate via ZnO nanowire as an in situ sacrificial template without using any strong acid or alkali. Importantly, both SnO2 α-Fe2O3 contribute storage, hybridization into integrated structure provides them elegant synergistic effect when...

In compound o-Cz donor acceptor units are connected at ortho position benzophenone, showing intramolecular space charge transfer. Therefore,...

Abstract To achieve highly‐efficient organic light‐emitting diodes (OLEDs), great efforts have been devoted into constructing thermally activated delayed fluorescence (TADF) with high horizontal dipole ratios (Θ // ). Here, we proposed a design strategy by integrating rigid electron‐accepting oxygen‐bridged boron core triple electron‐donating groups, which exhibited “shamrock‐shape”, namely BO‐3DMAC and BO‐3DPAC. Benefiting from the large‐planar skeletons brought shamrock‐shaped design,...
