Phosphorus-containing polymeric materials have been extensively studied in both scientific and industrial fields due to their unique properties. Among the wide variety of the phosphorus-containing materials, this review focuses on the synthesis and properties of the polymeric materials containing phosphine sulfide (P=S) groups. Because the P=S group has some unique properties, such as good thermal and chemical stability, coordination ability to transition metals, high molar refraction, and low polarity, the polymers containing the corresponding groups have been applied to flame retardant materials, polymer ligands, high refractive index materials, low birefringent materials, and low dielectric materials, some of which exceed the performance of conventional phosphorus-containing polymeric materials. Moreover, network polymer materials containing P=S groups will be growing interest for their practical use in electronic and optical fields.
