azophenols; thermalisomerisation; Introduction
Nowadays, there is an ever growing interest in molecular switching materials because of the very rapid development of modern technology. This tendency arises from the great applicability of such systems as active data elaboration, storage and communication
directly related with the thermalisomerisation rate of the photo-sensitive azo-dye in the dark, that is, with the relaxation time of the cis isomer of the azo-moiety. Slow thermally back-isomerising azoderivatives are valuable photoactive basic materials for information storage (memory) purposes. A
photomagnetic actuating purposes [38].
In this review, we present the efforts made in our research group over the past few years regarding the molecular design of new photosensitive azoderivatives endowed with very fast cis-to-trans thermalisomerisation processes, with the main aim of transmitting optical
