Further evidence for spontaneous solid-state polymerisation reactions in 2,5-dibromothiophene derivatives
Journal of Materials Chemistry(2003)
摘要
Three new, highly crystalline 2,5-dibromothiophene compounds polymerise on standing in the absence of solvent and catalyst; X-ray crystallography shows that the molecules are held in close proximity by several short intermolecular contacts, facilitating the coupling of monomers.
