This contribution also includes the implementation of cocrystallization for various categories of compounds which includes nutraceuticals, pharmaceuticals and ionic salts for the design and synthesis of molecular and ionic cocrystals. Chapter 1 highlights how supramolecular synthon approach can be used to design and synthesize multi-component crystals, namely, cocrystals. The role of the CSD and its importance in crystal engineering has also been discussed. Chapters 2 and 3 focus on new persistent supramolecular synthons in the context of nutraceuticals. The cocrystals isolated in the study are also compared with the existing cocrystals in the CSD supramolecularly in terms of synthon formation. These persistent supramolecular synthons are helpful in developing hierarchies which could be utilized and applied to similar and analogous compounds. The main feature of Chapter 4 is expanding the field of cocrystallization by studying the properties of cocrystals. Some of the properties which have been examined here include effects of cocrystallization on solubility and correlations between the solubility of cocrystal with cocrystal former (CCF) and melting point of the cocrystal. The extension of cocrystals to the active pharmaceutical ingredients (APIs) has been explored in the context of pharmaceutical cocrystals by selecting a BCS class IV drug, hydrochlorothiazide in Chapter 5. Chapter 6 highlights the hybridization of organic and inorganic components for the synthesis of ionic cocrystals and is exemplified by considering lithium salts with achiral and homochiral amino acids for the generation of 1:1 and 1:2 cocrystals.

Enhancing the physicochemical properties of solid-state materials through crystal engineering enables optimization of these materials without covalent modification. Cocrystals have become a reliable means to generate novel crystalline forms with multiple components and they exhibit different physicochemical properties compared to the individual components. This dissertation exemplifies methodologies to generate cocrystals of active pharmaceutical ingredients (API's) based upon knowledge of supramolecular interactions (supramolecular synthons), while focusing on enhanced delivery through in vitro and in vivo processes with both salts and cocrystals respectively. Different multiple component crystalline entities were discovered through traditional solution based techniques and with mechanochemistry involving small amounts of an appropriate solvent, or solvent drop grinding (SDG). Dissolution studies and pharmacokinetic enhancement through optimized oral drug delivery via supramolecular complexes are presented with particular attention to non-covalent intermolecular interactions.
