<br/>A surprisingly broad array of problems in modern materials chemistry relate to creating interfaces with two distinct, well-structured chemical environments at near-molecular scales. For instance, positioning nm-wide metal and semiconductor features with a pitch of 5-7 nm in a structured matrix represents a central requirement for next-generation electronic devices.  2D materials noncovalently functionalized with striped phases of amphiphiles present functional patterns at scales relevant for templating deposition of other materials for device applications. We find that assembling striped phases from diyne phospholipids creates interfaces with very different properties than simple diynoic acids or diyne amines. In part, this difference appears to arise from strong, orientable headgroup dipoles found in phospholipid headgroups, which confer function based on collective interactions similar to those in the cell membrane periphery. We will discuss the relationship between structure and function at striped phospholipid interfaces, and useful material properties that emerge from the unusual surface chemistry, including the assembly of inorganic nanocrystals.<br/>
