Abstract

Modulating the electronic, magnetic and optical properties at the molecular level using an external trigger has been extended to the field of nonlinear optics. The switching molecule is designed to have a complexation site or a redox active unit which can guarantee electronic communication over the whole conjugated system. The alteration of the nonlinear property is then induced by the modulation of the internal charge-transfer due to the response of the molecule to the external stimulus. This can be achieved by cation binding, protonation/deprotonation or electrochemically.
