Photoinduced reversible trans–cis isomerisation of an azobenzene amphiphile bearing dialkyl side chains in Langmuir–Blodgett membranes

Reversible trans–cis isomerisation is induced by UV and visible-light irradiation for Langmuir–Blodgett (LB) membranes composed of an azobenzene amphiphile bearing bulky dialkyl side chains.
