Peripheral crowding, rosette formation

The most stable aggregate of Whitesides rosettes family shown in Table 3.1 uses a combination of preorganization (sideways connection of the cyanurate subunits) and peripheral crowding of the melamine subunits for the preferential formation of... 

Figure 2. Schematic representations of preorganization of three melamine by covalent attachment to a center hub (left) and the formation of a rosette structure due to large groups (depicted here as spheres) by peripheral crowding (right). Melamines and cyanuric acid are represented as disks.
