This research aims to develop schemes for the programmed assembly of molecular materials. The underlying premise guiding this work is that structural information stored in the molecular constituents dictates their condensed phase organization (i.e. through the sum of all non‐covalent interactions). The challenge then is to design molecular building blocks that encode this information in a decipherable manner. Our approach has relied on the use of organic nanoarchitectures, which we believe will serve as “modular units” for programmed assembly. Large molecules of well defined constitution and geometry offer the advantage that a high level of information can be incorporated into a single unit. The design and synthesis of nanoscale macrocyclics and macrobicyclics for this purpose has been achieved. Studies on the solution aggregation of the macrocyclics have provided a unique opportunity to glimpse some of the interactions which may influence solid state ordering. These building blocks are being used for the rational design of novel materials such as porous organic crystals and tubular mesophases.
