Direct Observation of Aggregation‐Induced Emission Mechanism

Angewandte Chemie - International Edition, 2020
AbstractThe mechanism of aggregation‐induced emission, which overcomes the common aggregation‐caused quenching problem in organic optoelectronics, is revealed by monitoring the real time structural evolution and dynamics of electronic excited state with frequency and polarization resolved ultrafast UV/IR spectroscopy and theoretical calculations.

Aggregation induced emission – emissive stannoles in the solid state

Chemical Communications, 2020
For the first time, six classical stannoles with photoluminescence quantum yields of up to 11.1% in the crystalline state and 24.4% in the thin film state are presented.

Organic Mechanoluminescence with Aggregation‐Induced Emission

Chemistry – An Asian Journal, 2018
AbstractMechanoluminescence (ML) involves the emission of light from various organic and inorganic materials upon mechanical stimulus. In this review, we contemplate the advances of metal‐free, purely organic ML compounds with aggregation‐induced emission (AIE), which give strong emission upon mechanical force.

Fluorescent Polymersomes with Aggregation-Induced Emission

ACS Nano, 2018
Fluorescent 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 ...

Aggregation-induced emission—fluorophores and applications

Methods and Applications in Fluorescence, 2016
Aggregation-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 ...

Aggregation-induced emission luminogens for RONS sensing

Journal of Materials Chemistry B, 2020
The development of AIE bioprobes for RONS sensing in living systems is now summarized. We discuss some representative examples of AIEgen based bioprobes in terms of their molecular design, sensing mechanism and sensitive sensing in vitro and in vivo .
