Abstract: There are many modification sites, such as carboxyl, double bond and benzene ring electric-rich center in the structure of rosin acids. Rosin based derivatives with abundant hydrophilic groups have been obtained by chemical modification. Rosin acids and their derivatives show special self-assembly ability in solutions because they are composed of carboxylic acid, new hydrophilic groups and the unique hydrophobic skeleton, chiral structure of rigid tricyclic terpenes. As a result, rosin and rosin-based derivatives have many functions including high surface activity, smart responsiveness and targeted drug delivery by self-assembly of molecules. According to the structural characteristics of the compounds, the self-assembly of resin acids and their derivatives in small molecules, supramolecules, macromolecules and organic-inorganic hybrid molecules is reviewed. The self-assembly aggregates are analyzed. The self-assembly behaviors and characteristics of resin acids and their derivatives are summarized. The applications in surface activity, smart responsiveness, drug delivery and modification of inorganic nanomaterials are overviewed. Finally, the developments on functional materials and self-assembled aggregates of resin acids and their derivatives are prospected.
