| Research Abstract |
In this study, we aim to control of chirality in crystalline state via polymorphism of organic crystals.
Aromatic sulfonamides derivatives which have hydrogen-bonding sites were synthesized. These compounds gave chiral polymorphs. Cocrystal of an adamantane-based bisphenol with a bispyridine derivative formed a helical 1D chain via intermolecular hydrogen bonds. The thermodynamically metastable crystalline phases of two ionic liquids (1-alkyl-3-methylimidazolium hexafluorophosphate salts) were obtained by crystallization from the melt. The relationships between crystal structures and thermal properties of these ionic liquids are established.
