The invention provides an immunoconjugate comprising (a) an antibody construct comprising (i) an antigen binding domain and (ii) an Fc domain and (b) 1-8 adjuvant cores, wherein each adjuvant core is covalently bonded to the antibody construct via a linker, wherein each adjuvant core comprises a 2-amino nitrogen moiety with a pendant nitrogen atom and a point of attachment of the linker to the adjuvant core, and wherein the distance between the pendant nitrogen atom and the point of attachment of the linker is greater than about 5 Å. The invention also provides methods for treating cancer with the immunoconjugates.
