Abstract
Bis(10-phenyl-9-dianthryloxy)methane has been designed and synthesized to s erve as an excimer fluorescence probe taking advantage of the remarkable fl exibility of the chain linking the two aromatic rings. Spectroscopic study and transient kinetic analysis have been performed in media of various pola rity and viscosity. The dual fluorescence (monomer/excimer) is markedly aff ected by the viscosity of a series of silicon oils (polydimethylsiloxanes).
