摘要
The conditions for reliable preparation of bulk PB-1 samples inform III were established. The crystal structure of solution-prepared PB-1 samples was measured by X-ray diffraction as a function of solvent used, solution concentration, temperature of solution preparation, and solvent evaporation or solution precipitation. Measurements at higher temperatures revealed the crystallization of form III to I at temperatures below 95 degrees C and to form H at temperatures above 95 degrees C.
