Summary & Conclusions

• Dendrimers exhibit rich behavior at surfaces & interfaces

• Adsorption to hydrophobic surfaces despite strong interaction with water

• Significant compression along surface normal upon physisorption

ï Future Directions:

_ Imaging in nonpolar solvents (e.g., phenyloctane)

_ Submolecular resolution (low-current STM)

_ Dendrimers with enclosed guest molecules (FeOx nanoparticles ?)

ï Formation of dried films:

_ Drying process breaks up aggregates (isolated dendrimers / film)

_ Important role of residual water (flattening & expansion)

• Investigated self-assembly in solution:

_ Near-universal formation of large, oblate aggregates

_ Aggregates form & reside exclusively at interface

_ Weak dependence on solution parameters
