“Irregular” aggregation-induced emission luminogens
Coordination Chemistry Reviews, 2020Abstract Highly efficient luminescent materials have garnered considerable interest due to their special photophysical properties and potential applications. Aggregation-induced emission (AIE) is a photophysical phenomenon, in which concentrated or aggregated molecules produce enhanced light emission. In this review, we will introduce recent articles

Fluorescent Polymersomes with Aggregation-Induced Emission
ACS Nano, 2018Fluorescent polymersomes are interesting systems for cell/tissue imaging and in vivo study of drug distribution and delivery. We report on bright fluorescent polymersomes with aggregation-induced emission self-assembled by a series of tetraphenylethylene (TPE)-containing amphiphilic biodegradable block copolymers, where the hydrophilic block is a ...

Piezochromic aggregation-induced emission materials
SCIENTIA SINICA Chimica, 2013Aggregation-induced emission molecules have a common propeller-like twisted conformation feature, which makes their molecular packings relatively loose. Their crystalline structures are easily destroyed by the planarization of the molecular conformation under external pressure, resulting in increased molecular conjugation, thereby facilitating a red ...

Aggregation-induced emission—fluorophores and applications
Methods and Applications in Fluorescence, 2016Aggregation-induced emission (AIE) is a novel photophysical phenomenon found in a group of luminogens that are not fluorescent in solution but are highly emissive in the aggregate or solid state. Since the first publication of AIE luminogens in 2001, AIE has become a hot research area in which the number of research papers regarding new AIE molecules ...

Mechanochromic Luminescence of Aggregation-Induced Emission Luminogens
The Journal of Physical Chemistry Letters, 2015Mechanochromic (MC) luminogens have found promising applications in mechanosensors, security papers, and optical storage for their change in emission behaviors in response to mechanical stimuli. Examples on MC luminescent materials are rare before the discovery of MC luminescence in aggregation-induced emission (AIE) luminogens.

Cu Nanoclusters with Aggregation Induced Emission Enhancement
Small, 2013AbstractA facile and versatile method for preparing water‐soluble, stable, luminescent Cu nanoclusters (NCs) via the process of size‐focusing etching from nonluminescent nanocrystals is presented. Using glutathione as a model ligand, the smallest cluster, Cu2, is selectively synthesized to form a nearly monodisperse product, eliminating the need for ...
