research papersresearch papersAnalysis of COF-300 synthesis: probing degradation processes and 3D electron diffraction structure
Detailed analysis of the influence of time and temperature on the synthesis of COF-300 showed partial linker degradation but still allowed 3D electron diffraction structure solution using optimized conditions.
research papersEvolution of structure and spectroscopic properties of a new 1,3-diacetylpyrene polymorph with temperature and pressure
A new polymorph of 1,3-diacetylpyrene that is luminescent in the solid state and a prominent negative thermal expansion material has been obtained from its melt. A thorough structural characterization of this new crystal form was performed in a wide temperature and pressure range using single-crystal X-ray diffraction. Structural studies have been combined with steady-state UV–Vis spectroscopy and periodic density functional theory calculations. A previously published methodology of crystal placement in a diamond anvil cell has been successfully applied in predicting optimal 2°AP-β sample orientation, ensuring >80% data coverage and enabling unrestrained Hirshfeld atom refinements for high-pressure structures as well as analysis of anharmonic oscillations.
