Abstract
The time-resolved photophysical behaviour of α,α-dinaphthylpropane (αα-DNP) in iso-octane solution at temperatures greater than 30°C is in good agreement with the predictions of Birks kinetics. At temperatures below 30°C the fluorescence decay behaviour is more complex. This has serious implications for the attempted use of αα-DNP (or indeed any other bichromophoric compound) in attempts to probe macromolecular dynamics if 'forced fits' to dual-exponential functions were to be employed. The complexity of the fluorescence decay behaviour of such a simple model molecule (in which the complication of 'tacticity' and/or energy migration effects are obviated) has implications regarding the interpretation of the photophysical behaviour of macromolecules derived from vinyl aromatic monomers.
