Abstract

Considerable attention has been focused on the design and physicochemical studies of polyfunctional crown compounds and related supramolecular systems that are capable of operating as optical molecular sensors or photocontrolled ionophores. Crown ether-based optical molecular sensors are expected to be used in compact devices for colorimetric or luminescent analysis of metal ions and some organic cations. The application areas for photocontrolled ionophores include development of new ion-conducting light-sensitive materials, photocontrolled ion transport and ion separation, design of photoswitchable molecular devices and machines. In this paper we briefly review the main design concepts for crown ether-based optical molecular sensors (colorimetric and luminescent indicators) and photocontrolled ionophores.
