Calixarenes, along with calixcrowns are valuable receptors are used in many areas. An advantageous feature of calixarenes is their easy synthesis and functionalisation. The modification of calixarene structure offers a variety of new interesting tailor-made species, promising for a variety of applications; one should mention here possibilities of chiral recognition. Calixarenes and calixarene assemblies receive a growing attention today due to their properties allowing applications in various fields. This book is divided into two chapters dealing with covalently and non-covalently bound calixarene assemblies.
