The Institute of Chemistry of New Materials has developed chiral dopants for liquid crystals (LCs) based on products derived from the chemical modification of domestic wood-chemical raw materials. A wide range of chiral compounds was synthesized from a domestic wood-chemical product—pine gum rosin. It was established that maleopimaric acid amides and imidoamides—containing *para*-alkyl (alkoxy, bromo) phenylamide moieties and mesogenic groups (such as 4-biphenyl or 4-phenylaminobenzylidene)—exhibit high twisting power and good compatibility. These compounds can serve as dopants for nematic LCs in the preparation of chiral LC compositions. The synthesized compounds possess a twisting power ranging from 1.3 to 32.5 µm⁻¹, enabling the preparation of LC compositions with a helical pitch of 0.83–80.0 µm and the production of LC cells with electrically controllable light transmission.

Field of application: Electronics—production of LC materials and LC displays for various functional purposes.

The dopants are synthesized from naturally occurring chiral starting materials (rosin acids), thereby avoiding the need for costly asymmetric synthesis and separation methods. The resulting dopants are characterized by high twisting power, compatibility with nematic liquid-crystal matrices, and stability against light and heat.

The technical level is comparable to that of foreign counterparts.
