Perylene diimides (PDIs) and naphthalene diimides (NDIs) can be efficiently aminated with primary or secondary amines under mild conditions using Cu(II) salts as catalysts and air as an oxidant. Depending on the substrate and the amine, yields over 80% can be obtained by simply stirring the reaction mixture at room temperature for one hour.
A water-soluble perylenediimide (PDI) cyclophane consisting of a central PDI chromophore enclosed by double cationic molecular straps has been synthesized. Owing to the effective spatial isolation, self-aggregation of the chromophore in water is completely eliminated, which enables the cyclophane to be employed for lysosome-targetable live-cell imaging and antibacterial applications.
