Description
Summary:The fluorescence chemosensing behavior of Zn( ii ), Cu( ii ), and Cd( ii ) based complexes toward cations has been described. Cation detection via conventional mechanisms, metal-metal exchange and chemodosimetric approaches along with the importance of metal ions and the scope, significance, and challenges with regard to the detection of cations by metal complex based probes will be discussed in detail. The fundamentals of photophysical behavior and mechanisms involved in the fluorescence detection of analytes will also be described. This article provides a detailed overview of Zn( ii ), Cu( ii ), and Cd( ii ) based complexes as fluorescent probes for cations, together with essential discussions pertaining to detection mechanisms. Fluorescence chemosensing behavior of Zn( ii ), Cu( ii ), and Cd( ii ) complexes for detection of cations emphasizing conventional, metal-metal exchange and chemodosimetric mechanisms has been described conferring their scope, significance and challenges.
