We report the solid-state structural properties and phase transition behaviour of 1,4-dibromo-2,3,5,6-tetramethylbenzene, demonstrating that this material undergoes an order-disorder phase transition below ambient temperature (at ca. 156 K on cooling and ca. 159 K on heating). In both the high-temperature and low-temperature phases, the crystal str...

The X-ray Birefringence Imaging (XBI) technique, first reported in 2014, is a sensitive method for spatially resolved mapping of the local orientational properties of anisotropic materials. We report the first...

Members of a homologous family of 1:2 co-crystals comprising even-chain α,ω-dihydroxyalkanes and urea have been reported previously to fall into three well-defined structure types, although surprisingly polymorphism was not observed for any member of this series. Here we report the discovery of the first examples of polymorphism within this family...

Establishing the use of X-ray birefringence imaging (XBI) to study local anisotropy in materials, at the copper k-edge.

Semiconducting O-doped polycyclic aromatic hydrocarbons constitute a class of molecules whose optoelectronic properties can be tailored by acting on the π-extension of the carbon-based frameworks and on the oxygen linkages. Although much is known about their photophysical and electrochemical properties in solution, their self-assembly interfacial b...

The X-ray birefringence imaging (XBI) technique, first reported in 2014, is a sensitive method for spatially resolved mapping of the local orientational properties of anisotropic materials. In the case of organic materials, the technique may be applied to study the orientational properties of individual molecules and/or bonds, including the study o...
