A novel AIEgen with prominent two-photon excitation was rationally developed for specific lipid-droplet imaging in cells and tissues.
A liquid crystalline molecule tetraphenylethylene-PPE with aggregation-induced emissive characteristics is synthesized. Anisotropic emission obtained through the dissolution of tetraphenylethylene-PPE into nematic crystals. Two types photoluminescent display devices are fabricated mixture. This approach provides a path for building energy-saving light-emitting crystal that avoid aggregation-caused quenching problem.
Abstract Luminogens with aggregation‐induced emission characteristics (AIEgens) are intriguing due to its rapid expansion in various high‐tech applications. However, there is still high demand on the development of novel AIEgens easy preparation and functionalization, stable structures, tunable emissions, quantum efficiency. In this contribution, three based diphenyl isoquinolinium (IQ) derivatives reported. They can be facilely synthesized possess structural stability, favorable visible...

Noteworthily, two molecules o-TPA-3TPE-o-PhCN o-TPA-3TPE-p-PhCN with larger ΔEST values (0.59 eV 0.45 eV, respectively) emitted efficient long-lived low temperature glassy solutions exhibited crystallization-induced room (RTP). Meanwhile, it...

<title>Abstract</title> Solid film capacitors play a crucial role in the modern electrical and electronic industry, with organic polymer materials dominating market owing to their cost-effectiveness exceptional processability. However, low dielectric constants of current polymers gradually fail meet increasing demands for high energy density capacitors. Improving storage capacity films is imperative yet very challenging. This work synthesizes an aromatic polyimine (API) crystallinity unique...

Visible light communication (VLC) is an emerging technology that can transform lighting facilities into access points for wireless communication. Its development bottlenecked by the cut-off frequencies (e.g., -6-dB electrical frequency f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">c</sub> and -3-dB xmlns:xlink="http://www.w3.org/1999/xlink">-3 dB</sub> ) of hardware, such as light-emitting diodes (LEDs), color converters, photodetectors...
