Abstract
The fluorescence of pyrene has been studied as a function of pressure, concentration and temperature in the solvents ethanol and cyclohexane. The spectra and lifetime of both monomeric pyrene and the excited state complex are characterized at different pressures. Compression of ethanol shifts the monomer-excimer equilibrium towards the monomer, while compression of cyclohexane leads to aggregation and pyrene excimer fluorescence over a large concentration range.Keywords
