Photophysics of supramolecular architectures

Book Announcement

Bentham Science Publishers

The intense research in the fields of photochemistry and its applications in understanding the photosynthetic processes and solar energy conversion via chemical routes lead to the growth of ‘supramolecular chemistry’, known as ‘chemistry beyond the molecule’. The last four decades witnessed an explosion of research activities in the application of supramolecular assemblies in photophysics and photochemistry of molecules and the importance of supramolecular chemistry was understood after the award of 1987 Nobel Prize for Chemistry (Nobel Laureates: Donald J. Cram, Jean-Marie Lehn and Charles J. Pedersen) in this area of research. Supramolecular architectures are the prevalent architectures in nature are designed through a variety of non-bonding interactions like hydrogen bonding, p-p staking, self-assembly etc. From physics to biology, the functionalities of supramolecular architectures play an important role. For example, the life is not possible without a DNA folding or protein self-assembly.

The book “Photophysics of Supramolecular Architectures” mainly focuses on cavity containing supramolecular hosts and their photophysical properties. The host-guest chemistry is a widely established subject which can expand as an individual field of research with respect to the cavitand. The host-guest chemistry is envisaged as mimic for enzymatic catalysis. Also, they are used as drug delivery vehicles for the targeted payload delivery in medicinal chemistry and biotechnology.

The study of the interaction of guest molecules with light in the presence of host molecule opens a research opportunity to make advanced research like optical tweezers.  

The recent studies of photophysics of guest molecules with various cavitands like cylclodextrin, calixarene and their derivatives, cucurbiturils are highlighted in this book. The cyclodextrin complexes having different cavities and encapsulation of fluorescent guest molecules and applications of these systems are elaborately discussed in Chapter 1. Chapter 2 deals with the interaction of fluorescent guest molecules with calixarenes and their applications towards sensors. The photophysical properties of coordination complexes of calixarene-lanthnide systems are also discussed in this chapter. Resorcinarene, one of the important molecules in the calixarene family, receive importance for their hydroxyl group containing upper rim, which makes suitable for catalysis applications. This Chapter 3 mainly focuses the upper rim modification at hydroxyl group to achieve crown ethers. Even though, the crown ethers are separately known as supramolecules, this chapter discussed upper rim modified resorcinarene-crown and their applications using optical spectral techniques. Chapter 4 deals with the pillararenes, which are considered as young cavitand molecular system, reported only in 2008. This chapter discussed the host-guest chemistry of pillararenes with fluorescent guest molecules. The self-assembly of pillarene derivative are also discussed to achieve sensor applications. Chapter 5 is concerned with the molecular recognition of fluorescent molecules encapsulated cucurbiturils and applications as sensors. The application towards imaging and photodynamic theraphy using cucurbiturils systems are also discussed. Chapter 6 discussed the control of photophysical properties and photochemical events of various cavities and capsules. Chapter 7 mainly focuses on the carrying metal complexes, i.e., metallacycles. The various cavity structures of metallacycles are discussed in detail. The rhenium based metallacycles and their molecular recognition properties are discussed. Chapter 8 deals with the dynamics of macromolecules functionalized with fluorescent molecules. The macrocyclic environment acts like a host molecule and influences the optical properties of the functionalized fluorescent molecule. The folding and unfolding of macrocycles exhibit substantial variations in the fluorescent molecules. This book strives to give collectively the applications of host-guest chemistry with recent applications. The recent advancements in the various host-guest systems will provide newer insights to readers in both conventional host molecules like cyclodextrin as well as in young host molecules like pillararenes. This book is a single source of collection of literature on the chosen topic and will help the young researchers to understand the field of research, up-to-date literature and plan their future plan of action in the areas of supramolecular systems and their applications in photophysics and photochemistry.
