Abstract
Crystallization of organic compounds is of great industrial and academic importance. It affects many properties of functional materials such as the dissolution kinetics, self-assembly, purity, and electronic and optical properties, to name a few. Therefore, understanding and establishing control over the thermodynamic states of such organic compounds is imperative, especially for pharmaceutical and electronic applications. The proposed research investigates the multi-faceted phase behaviors of crystallizable small molecule organic compounds with a library of polymers by extensive characterizations using differential scanning calorimetry (DSC), X-ray scattering, and fluorescence emission spectroscopy. In the first part of this research, the thermal miscibility between the polymers and the small molecule organic compounds was studied from the viewpoint of the melting temperatures of the organic crystals in the mixtures. The second part involved developing a consistent method for the measurement of the phase separated compositions and understanding the effect of different heat treatment procedures on the phase states of the mixtures. Finally, the thermodynamic interactions between the polymers and the organic crystals were probed from the standpoint of crystallization of the organic compounds.
