Abstract
We designed a supramolecular complex consisting of a dipicolylamine copper complex with an azobenzene group and phenylboronic acid-modified cyclodextrin for adenosine 5′-diphosphate (ADP) recognition in water. Evaluating its phosphate recognition ability through UV–vis and induced circular dichroism spectroscopy demonstrated high selectivity and a large binding constant for ADP in water. Further investigation into the recognition mechanism suggested that the high sensitivity is due to the formation of a supramolecular complex through a combination of four weak interactions.
期刊介绍:
Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied.
Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media.
The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
