| Popis: | In this chapter, we highlight the quantitative aspects of metallic ion sensing by photochromic spiro-compounds dyes. In the simplest case, spiro-compound—metal complexation can be described by only two equilibria. The first one is the closed spiro to open merocyanine thermochromic equilibrium, the second one is the metallic complex formation where the open merocyanine plays the role of a ligand. We supply a compilation of the structural, spectroscopic, thermodynamic and kinetic aspects of the most quantitatively analysed metal complexing spirocompounds. Several spiro-compound-based metal sensing systems and devices are described. By examining these examples, it appears that besides increasing the dye’s complexity to improve its selectivity for a specific ion, other promising approaches to achieve detection by differential sensing and chemometric analysis are in progress. |
