Flick of a switch: The nonlinear optical (NLO) response of three π-conjugated azobenzene (AB) derivatives is investigated to evaluate the effect of an ethynyl-based conjugated spacer on the NLO properties of ABs. A cis-isomer-dependent increase of the NLO response, together with intrinsic structure-related high hyperpolarizability values, determined these compounds superb candidates for ultrafast switching NLO devices.
