Coordination-driven
self-assembly provides unique opportunities to prepare highly complex chemical
systems from simple components and has led to significant progress in the
construction of supramolecular materials with novel topologies and exploitable
functions. During the past few decades, metallacycles have captured widespread
interests due to their wide applications in catalysis, sensor, and biological relevant
applications. Thus, exploring new metallacycles, studying their physical and chemical
properties and applications have become one of the most attractive and exciting
areas of inorganic chemistry and supramolecular chemistry. Among which, rhenium(I)-based
metallacycles, constructed from the rhenium metal ions and a variety of
aromatic ligands, have attracted considerable attention because of their unique
potentials in light-harvesting, catalysis, sensing, biomedical, etc. In this
chapter, we summarize the recent research progress in rhenium-based
metallacycles with their synthesis, properties and potential application in
host-guest chemistry.
