The development of fluorescence sensor for detection of cations and anions is a well-established area in modern chemistry because of their immense analytical application in many areas including biology and chemistry. Calix 4]arene based chemosensors have attracted great deal of attention due to their ability to visually sense analytes with high sensitivity as well as fast response time logy and chemistry. Fluorescence technique is widely used for recognition of cations and anions due to its distinct advantages in terms of sensitivity, selectivity, response time and in situ monitoring. Here in...

The development of synthetic receptor for cation and anion recognition have attracted considerable attention in recent years within the field of supramolecular chemistry due to the fact that a large number of biological processes involve molecular recognition.The leading issue in the design of any active chemosensor is the connotation of a selective molecular recognition event with a physical signal highly sensitive to its occurrence. Fluorescence technique is commonly considered superior than other electrochemical techniques because of its low detection limits for trace chemical detection,...

Research on molecular recognition of amino compounds, such as biogenic amines, amino acids, peptides, proteins, and carbohydrate like essential substrates in biological processes, by synthetic receptors is an issue of great concern from both a supramolecular chemistry and analytical application point of view. Among naturally occurring amino acids tryptophan (L-Trp) is the most fluorescent, the indole ring of L-Trp have recently been the subject of much investigation due to the functional and structural prominence of such interactions in chemistry and biology. Recently, it was found that the...

Calix n]arenes represent an interesting class of preorganized aromatic hosts exhibiting an enhanced ability for cation- interaction. In many biological systems, metal cation- interactions play an important role in molecular recognition. Interest has focused on the interaction between organic cations in both natural and synthetic receptors. Systematic studies of a series of related structures of artificial receptor molecules have revealed the role played by cation- interactions. Calixarenes and related skeletons are a widely used platform in order to study cation- interactions. This book...
