The present disclosure provides for new photoalignment (co)polymer materials which demonstrate improved adhesion to a substrate. The (co)polymeric structure includes at least one photochemically active chromophore and at least one adhesion promoter group. Articles of manufacture, optical elements, ophthalmic elements and liquid crystal cells which include at least one photoalignment layer made from the photoalignment (co)polymer materials and methods for formation are also disclosed.
Hydridopalladium(II) species generated in situ by oxidative addition of Pd(0) to acetic acid or acidic hydroxyl substrates (phenols, oximes) catalyse the termolecular assembly of allenes, CO and amines (primary, secondary) or oxygen nucleophiles to give methacrylamides or methacrylate esters and derivatives thereof in good to excellent yield.
