Second harmonic generation in ferroelectric liquid crystalline thiadiazole derivatives

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. magnified image
