Abstract: Complex microstructures assembled with ABC amphiphilic nanoperticle-coil macromolecules are investigated with an extending serfconsistent field theory (SCFT) and density functional theory (DFT). The tail of macromolecule is an AB dibiock copolymer, and the attached "head" is a nanoparticle in dilute solution. Serf-assembly morphologies of ABC "tadpole" are different from aggregate morphologies of linear ABC triblock copolymers. As nanoparticle is hydrophilic, spherelike micelles are observed in a weak segregation state. While interaction between different species of "tadpole" increases to a strong segregation state, aggregate morphologies of tadpole transform from spherelike micelles to quadrangle or triangle micelles with increasing of hydrophobic property of blocks A and B. In this case, block B is distributed in corners of quadrangle or triangle micelles. As block A is hydrophilic, hydrophobic nanoparticle assembles into parallel rods or squares in spherelike micelles.
