A multistep single-crystal-to-single-crystal bromodiacetylene dimerization
Nature Chemistry, 2013 Packing constraints and precise placement of functional groups are the reason that organic molecules in the crystalline state often display unusual physical or chemical properties not observed in solution. Here we report a single-crystal-to-single-crystal dimerization of a bromodiacetylene that involves unusually large atom displacements as well as the

Acta Crystallographica Section E: Crystallographic Communications, 2023 The structural parameters of yttrium chromium tetraboride YCrB4 were refined based on single-crystal X-ray diffraction data. YCrB4 is orthorhombic, having a space group of type Pbam (No. 55) and with lattice parameters of a = 5.9425 (2), b = 11.4831 (4),

Photodriven single-crystal-to-single-crystal transformation [PDF]
Coordination Chemistry Reviews, 2017 Abstract Molecular architectures containing photosensitive units respond to light, giving dramatic variations of their structure. In particular, the crystalline packing phases offer the possibility of significant advances in crystal design and the understanding of solid-state photoreactivity.

Single-crystal two-dimensional material epitaxy on tailored non-single-crystal substrates
Nature Communications, 2022 The heteroepitaxial growth of crystalline 2D materials is usually based on single-crystal substrates. Here, the authors demonstrate that single-crystal graphene and hexagonal boron nitride films can be successfully grown on wafer-scale copper foils with ...
