Second harmonic generation in ferroelectric liquid crystalline thiadiazole derivatives

Authors


Abstract

Ferroelectric liquid crystals are of interest for applications in second order nonlinear optical experiments as they combine a thermodynamically stable polar structure with mobility. Low-molecular weight-(see Figure) and siloxane-fixed FLCs are reportd which contain a donor-acceptor π system in a heterocylic ring whic does not disturb the desired rod-like shape of the molecules.
