Abstract

The concept of photoinduced electron transfer has been explored for the development of polymeric transducers for optical ion-detection devices. For this purpose, a series of N-(9-anthrylmethyl)monoaza-18-crown-6 substituted poly(methacrylate)s were prepared, which differ in the chemical nature of the backbone. The fluorescent signaling in these systems is based on disturbances, upon complexation of K⊕, in the competition between de-excitation pathways of fluorescence and photoinduced electron transfer. The sensitivity and the ultimate enhancement of the fluorescence of these materials upon complexation of K⊕ were found to be strongly influenced by the chemical structure of the polymer backbone.

Chemical substance

A chemical substance is a form of matter having constant chemical composition and characteristic properties. Chemical substances can be simple substances (substances consisting of a single chemical element), chemical compounds, or alloys. Chemical substances that cannot be separated into their simpler constituent elements by physical means are said to be 'pure'; this notion intended to set them apart from mixtures.

Polymer

A polymer (ˈpɒlᵻmər; Greek poly-, "many" + -mer, "part") is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function.

Chemical structure

A chemical structure of a molecule is a spatial arrangement of its atoms and their chemical bonds. Its determination includes a chemist's specifying the molecular geometry and, when feasible and necessary, the electronic structure of the target molecule or other solid. Molecular geometry refers to the spatial arrangement of atoms in a molecule and the chemical bonds that hold the atoms together and can be represented using structural formulae and by molecular models; complete electronic structure descriptions include specifying the occupation of a molecule's molecular orbitals.
