Halogen bonded cocrystal polymorphs of 1, 4-di(4′-pyridyl)-1, 3-diacetylene. Issue 31 (19th July 2017) - Zhang, Pan
Abstract : Two cocrystals based on IFB and DPDA are controllably prepared under solvent effects demonstrating different photo-physical properties. Abstract : Cocrystal polymorphs based on sym -triiodo-trifluorobenzene (IFB) with 1, 4-di(4′-pyridyl)-1, 3-diacetylene (DPDA) are formed with halogen bond interactions. Two cocrystal phases were obtained by using different solvents, acetonitrile and methylene chloride, and confirmed by their single crystal structure data. In the application direction, the different photo-physical properties of the two phases were discussed carefully.
