Conference paper


Mechanically and opto–mechanically controlled azobenzene (AB) switch based on AB–metal break–junction have been studied using ab–initio simulations. It was found that both cistrans and transcis mechanically driven switchings in the lowest singlet state are possible. Bidirectional optical switching of mechanically strained AB through first excited singlet state was also predicted provided that the length of the molecule is adjusted towards the target isomer equilibrium length.
