Abstract
Most conventional luminophores produce intense emissions in solutions but suffer from weak emissions or quenching when aggregated in poor solvents due to intermolecular interactions, such as π-π stacking. This phenomenon is known as aggregation caused by quenching (ACQ), limits their applications in their solid state. In contrast, aggregation induced emission (AIE) is a phenomenon in which luminophores are weak- or non-emissive in solution but emit intensively in their aggregated or solid states. AIE has enabled significant advancements in various real-world applications and has inspired new areas of research. The combination of AIE with electrogenerated chemiluminescence (ECL) has resulted in a new physiochemical phenomenon termed aggregation induced electrogenerated chemiluminescence (AIECL). AIECL luminophores likely produce much enhanced ECL signals in mixed solvents or solid state as compared with their emissions in solution. This dissertation delves into four projects focused on investigating AIE-active ECL luminophores, their mechanistic understanding, structural property relationships and analytical applications.
