Abstract
Compositions providing metal-independent phosphorescence due to a directed heavy atom effect are provided. Methods of providing a phosphorescent composition are also provided where a directed heavy atom effect is maintained to cause the composition to be phosphorescent. Manufacture of phosphorescent compositions using intermolecular and intramolecular directed heavy atom effects are disclosed.
