softmatter:Tethered Building Block

From NSDL Materials Digital Library Soft Matter Wiki

Tethered building blocks constitute a class of “shape-amphiphiles” where microphase separation occurs due to the immiscibility between the tether and building block, similar to Block Copolymers and Surfactants. Building blocks can vary greatly, from metallic nanoparticles to molecular nanomaterials such as POSS or Porphyrin. Temperature, solvent quality, concentration, tether placement, number of tethers, building block geometry and composition, are only a few of the many parameters that can have a large impact on the resulting structures and phase behavior.
