The aromatic hydrocarbon pyrene is an important and thoroughly investigated organic chromophore. Among the characteristics that make pyrene attractive is its superior ability to form intermolecular excimers [1] in concentrated solution and in the solid state, as well as intramolecular excimers [2] independent of concentration. This excimer formation has been widely used to study the viscosity of micelles, phospholipids and biological membranes.[3 ...
