Summary

Supramolecular aggregation, driven by weak non-covalent interactions, such as van der Waals, π-π interactions, hydrogen bonding, electrostatic, etc. 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 provides recent advancement in Supramolecular Chemistry, in which the luminophores are almost non-luminescent in the molecular state, but become highly emissive in the aggregate state, brings 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 drug delivery field. The timely book covers the advances of aggregation in supramolecular systems, various interactions involved in the formation of supramolecular structures, stimuli inducing aggregation of luminophores, the photophysical phenomenon of aggregation, key mechanisms that generate new spectroscopic properties of aggregates and their applications.

Features :

  • Discuss fundamental and interdisciplinary aspects of aggregation in supramolecular systems.

  • Narrates intermolecular interactions and the photophysical phenomenon of aggregation in supramolecular systems.
  • Provides a comparative discussion on aggregation-induced quenching (AIQ) and aggregation-induced emission (AIE) in aspects of recent interest and drawbacks of AIQ.
  • Presents technological applications of aggregation as biological sensors, chemical sensors, organic electronic materials, and in the drug delivery field.
  • Uses a convenient format for checking formulas and definitions.

In this book, we survey highlights of the progress made in the field of aggregation of luminophores in supramolecular chemistry. It is our hope that the work will form a foundation (and indeed a motivation) for new workers in the area as well as also being useful to experience 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 in graduate, senior undergraduate, research professionals, and industry.
