Novel Fluorescent Reactive Dyes as ... - SpringerLink
Summary. To prepare reactive dyes matching the optical properties of 2-(1,1-dicyano-propenyl-2)-6-dimethylaminonaphthalene (DDNP), 2-ethylaminoethanol or 4-piperidinemethanol were used in a Bucherer reaction with 1-(6-hydroxy-2-naphthyl)-1-ethanone.The two amines were chosen to mimic the dimethylamino group’s steric and electronic (inductive) effects and to provide a reactive site for ligand ...
