Self Assembly 

Hao Yan, Ella King, Matt Gebbie

Diamondoids have remarkably strong intermolecular interactions arising from their steric bulkiness, low conformational entropy, and unexpectedly strong dispersive attraction. We harness these effects to guide the synthesis of low-dimensional inorganic-organic hybrid materials with atomically precise structural control that is unattainable in pure inorganic materials. This new class of materials offers the platform for a plethora of novel physics at low dimensions. We are also studying the molecular origin of the surprisingly strong forces between diamondoids using both experimental and computational approaches.

Image 1: Crystal structure of copper adamantanethiolate. The nanowire structure consists of copper sulfide cores with three-atom cross-section (yellow and brown), representing the smallest nanowire possible. The growth of the ultrathin inorganic core is guided by the strong intermolecular interaction of the diamondoids (blue).
