Recent Advances in Aggregation‐Induced Electrochemiluminescence

Abstract

The emergence of the rising alliance between aggregation‐induced emission (AIE) and electrochemiluminescence (ECL) is defined as aggregation‐induced electrochemiluminescence (AIECL). The booming science of AIE has proved to be not only distinguished in luminescent materials but could also inject new possibility into ECL analysis. Especially in the aqueous phase and solid state for hydrophobic materials, AIE helps ECL circumvent the dilemma between substantial emission intensity and biocompatible media. The wide range of analytes makes ECL an overwhelmingly interesting analytical technique. Therefore, AIECL has gained potential in clinical diagnostics, environmental assays, and biomarker detections. This review will focus on introduction of the novel concept of AIECL, current applied luminophores, and related applications developed in recent years.

Benzosiloles with Crystallization‐Induced Emission Enhancement of Electrochemiluminescence: Synthesis, Electrochemistry, and Crystallography

“…To the best of our knowledge, this is the first example where the ECL performance is demonstrated to improve significantly by CIEE. Previously, aggregation‐induced emission enhancement (AIEE) of ECL, also known as AIECL, as recently summarized by Xu has been reported for 1,1′‐disubstituted 2,3,4,5‐tetraphenylsiloles, carboranyl carbazoles, tetraphenylethylene nanocrystals, and platinum complexes, but the performance difference between amorphous aggregate and crystalline film states has not been clearly shown prior to this report on benzosiloles. Is CIEE‐ECL just an example of a well‐ordered aggregate?…”

Film Electrochemiluminescence Controlled by Interfacial Reactions Along with Aggregation‐, Matrix‐Coordination‐, and Crystallization‐Induced Emissions

“…Interested readers should also be directed to Yan, Lu and Xu et al.’s review on solution and film AIECL for further reading, [32] which covers AIECL advancements of polymer dots, [33] Ir complexes, [34] organic dots [35] and Pt complexes [36] . It should be noted, that De Cola, Hogan, Aliprandi and co‐workers discovered 20 times ECL enhancements of square planar Pt(II) complexes comparing solution to solid ECL in late 2017 and to the best of our knowledge, was the first to assign AIECL [36] .…”

Recent Advances on Fabrication of Polymeric Composites Based on Multicomponent Reactions for Bioimaging and Environmental Pollutant Removal

“…[ 106 ] It is worth pointing out that the definition of aggregation‐induced electroluminescence is based on both AIE luminogens and electroluminescence assays, which can provide a novel avenue in solid or aqueous media. [ 107 ] Many outstanding works have been reported on the preparation of aggregation‐induced electroluminescent polymers and their applications in the biomedical field. [ 108–111 ] In this work, P‐1 and P‐2 were prepared with two AIE active D‐A copolymers via the Suzuki reaction.…”
