Abstract

A red-emitting molecular europium(III) complex has been doped into liquid-crystalline (LC) physical gels consisting of 4-pentyl-4'-cyanobiphenyl (5CB) with amino acid-based gelators. Light scattering cells on the basis of these LC physical gels could be switched between a non-transparent off-state and a transparent on-state by on–off application of electric fields. The gels produced intense red light when they were irradiated with UV-light.
