Thermodynamics and Kinetics of Guest-Induced Switching between “Basket Handle” Porphyrin Isomers

open access: yesMolecules, 2014
The synthesis and switching properties of two “basket handle” porphyrin isomers is described. The cis-oriented meso-phenyl groups of these porphyrins are linked at their ortho-positons via benzocrown-ether-based spacers, which as a result of slow ...

2,3,4,5,6-Pentabromophenyl phenyl ether

open access: yesActa Crystallographica Section E Structure Reports Online, 2002
The title compound, C12H5Br5O, belongs to a group of flame retardants known as polybrominated di­phenyl ethers (PBDE). Salient features of the packing are stabilization due to intermolecular Br⋯Br contacts in the ab plane and aromatic intermolecular contacts along the c direction.
