Benzofuran Trimers for Organic Electroluminescence
Anderson, Sally,Taylor, Peter N.,Verschoor, Geraldine L. B.
, p. 518 - 527 (2007/10/03)
Four linear benzofuran trimers have been prepared by a two-stage synthetic procedure. They were tested as materials for organic electroluminescence (OEL). Precursor phenylene ethynylene oligomers were formed in the first stage, then after removal of the p
