Disclosed herein is a method of generating a combinatorial library of products having a diverse array of properties. In particular, the method comprises: (a) selecting one or more pairs of reactants comprising complementary functional groups; (b) mapping all possible bond arrangements between the complementary functional groups of each pair to provide a library of possible products; (c) analyzing one or more properties of each possible product to select one or more products with desired properties (desired products); and (d) synthesizing the one or more desired products. Further disclosed herein is a method that involves the retrosynthetic reduction of a complex molecule into simple starting materials.
