Physical stability enhancement of theophylline via cocrystallization

International Journal of Pharmaceutics, 2006
The crystal form adopted by the respiratory drug theophylline was modified using a crystal engineering strategy in order to search for a solid material with improved physical stability. Cocrystals, also referred to as crystalline molecular complexes, were prepared with theophylline and one of several dicarboxylic acids.

Cocrystallization‐Induced Red Ultralong Organic Phosphorescence

Angewandte Chemie International Edition
AbstractOrganic cocrystals formed through multicomponent self‐assembly have attracted significant interest owing to their clear structure and tunable optical properties. However, most cocrystal systems suffer from inefficient long‐wavelength emission and low phosphorescence efficiency due to strong non‐radiative processes governed by the energy gap law.

Cocrystallization of Brucine with Perfluorinated Iodobenzenes

Halogen bonding can be achieved with a wide range of potential acceptor atoms (N, O, S, halogenide, P, As, Sb etc.), the majority of halogen bonded crystal structures to date include nitrogen and oxygen as the halogen bond acceptor. [1] Polycyclic alkaloids often have multiple inequivalent nitrogen and oxygen atoms that can act as potential halogen ...
