Аннотация

Fluorescent photoswitchable systems (FPSS) are organic molecular and organic-inorganic hybrid nanoscale systems that combine the properties of photochromes and fluorophores, i.e. the ability to change their fluorescent properties, intensity and/or emission spectrum under the action of light. The structure and mechanisms of action of FPSS of different types are considered, examples of application of FPSS in super-resolution microscopy, for visualisation of biological and inorganic nano-objects, recording of optical information, for anti-counterfeiting, as photonic molecular logic gates are given.
