Supramolecular aggregation—driven by weak non-covalent interactions, such as van der Waals, π–π interactions, hydrogen bonding, and electrostatic—has been utilized to build sensing platforms with improved selectivity and sensitivity. Supramolecular aggregates, owing to cooperative interactions, higher sensitivity and selectivity, relatively weak and dynamic non-covalent interactions, and environmental adaptation, have achieved better sensing performance than that of molecular sensory systems that rely on sensors with delicate structures. Aggregation of Luminophores in Supramolecular System: From Mechanisms to Applications describes recent advances in supramolecular chemistry, in which the luminophores are almost non-luminescent in the molecular state, but become highly emissive in the aggregate state. These advances bring new opportunities and challenges for the development of supramolecular chemistry. The intermolecular non-covalent interactions have been considered to be the main driving forces for fabricating supramolecular systems with aggregating luminophores and have an important influence on the luminescence properties of the probes. Based on these unique properties, luminescent supramolecular aggregates have greatly promoted the development of novel materials for applications as sensors, bio-imaging agents, organic electronic devices, and in the field of drug delivery. Features: Discussion of fundamental and interdisciplinary aspects of the aggregation in supramolecular systems. Narration of intermolecular interactions and the photophysical phenomenon of aggregation in supramolecular systems. Comparative discussion on recent developments in aggregation-induced quenching (AIQ) and aggregation-induced emission (AIE), and drawbacks of AIQ. Description of the technological applications of aggregation as biological sensors, chemical sensors, organic electronic materials, and in the field of drug delivery. A convenient format for checking formulas and definitions. This book surveys highlights of the progress made in the field of the aggregation of luminophores in supramolecular chemistry. It is hoped that the work will form a foundation (and indeed a motivation) for new workers in the area, as well as also being useful to experienced supramolecular chemists. It may also aid workers in the biological area to see Nature’s aggregation in a new light. Further, the approach employed has been designed to provide readable background material for use with graduates, senior undergraduates, research professionals, and industries.

This book collects all the latest advances in the leading research of the circularly polarized luminescence (CPL) of small organic molecules. Compared with that of lanthanide-based fluorophores, the research into the CPL of small organic molecules is still at the developmental stage for their relatively smaller dissymmetric factors, but has been a source of widespread attention recently. The book includes the state of the art of the discoveries in CPL organic molecules, such as helicenes, biaryls, cyclophanes, boron dipyrromethene dyes, and other chiral molecules, mostly in their isolated states, covering all possible chiral substances for future applications. This book also highlights the recent development of CPL instruments as well as time-resolved circular dichroism spectroscopy, to facilitate the further development and future design of CPL molecules.

The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience.Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.The chapter "Aggregation-Induced Emission In Electrochemiluminescence: Advances and Perspectives" is available open access under a CC BY 4.0 License via link.springer.com.
