Amide-bridged ladder poly(p-phenylene): synthesis by direct arylation and π-stacked assembly†
Abstract
Amide-bridged ladder poly(p-phenylene) was synthesized in two steps, through the polycondensation of aromatic diamines and dicarboxylic acid derivatives followed by palladium-catalyzed intramolecular direct arylation. The π-stacked assembly of the polymer in solution was investigated along with the single crystal X-ray structure analysis of a model oligomer.
